Other endings:

Unlimited MP:
Have Amarant in your party and make sure he has learned the Chakra skill. Also, the minimum MP needed for this trick to work is 4 MP. Enter a battle and have Amarant cast Chakra on himself. For 4 MP, he will restore MP equivalent to about 20% of his maximum MP. Continually cast it until you get reached your maximum MP. Since you can do this to other characters in the party as well, you can end up will everyone with maximum MP.

Easy AP:
Walk around in the darkness for awhile in the field and forests around the town that has the Auction House and lady who collects the zodiac signs. You will encounter a ghost. Give it some ore and you will win the battle, resulting in 10 AP.

Go to the forest west of the mountain path when going to the Lifa Tree. It is the only forest there. Walk around in the forest until you encounter a friendly monster called "Ladybug". Give it some Ore and it will reward you with 30 AP.

With the Invincible, go to Popo mountains where the grand dragons are located. Walk around in the forest until you find a Garuda. He will ask for Lapis Lazuli. If you give it to him, you will win the battle and get 40 AP.

When you arrive at the Lost Continent, somewhere around Esto Gaza, you will encounter a friendly Feather Circle. Give him a Moonstone and you will get 50 AP.

Easy experience:
Use Quina's level 5 Death spell against the level 60 Grand Dragons on the outside of Gizamalike's Grotto for around 8800 experience per person. Equip the quick level gain support ability (level up) for even more. Also, remember to take Coral Rings to protect against the Dragon's Thundaga spell.

Find a Dracozombie. In Disc 4, you can find then on the small green patches of land near the Ipsen's Castle on the world map. You must have Zidane, Dagger or Eiko, Amarant, or Quina in the battle against Dracozombie (you can use others character if you needed). Have Dagger or Eiko use the Silence ability on Dracozombie, because it can cast the Lv 5 Death spell. Keep defending until all your characters are affected with the Zombie spell, then kill it. Use Magic Tag to cure the character that you want to level up quickly. Equip the Quick Level Gain support ability (Level Up) to make your character get more experience. You must disable the Auto-Regen and Auto-potion support ability on every character which is affected by the Zombie spell. You cannot use items to cure or use spell such as Cure, Cura, Curaga and White Wind on the affected character. Amarant's Chakra skill is essential, since it still works on the affected character.

When you finish beating the plant brain, right after you go out the door stay in the same location. Do not move and the creatures well keep appearing. They are easy to defeat and give a decent amount of EXP and AP.

Fight the monster called Yan or Chimera. When you fight this monster, keep defending until it drops or bites your party member and gives them viruses. Cure the person that you want to level up. Then fight a monster that has a lot of experience such as Grand Dragon, Iron Man, Vepal or Worm Hydra. Fight until the party member that was cured from the virus levels up.

Once you are on Disc 4 and have the Invincible Airship or a Gold Chocobo, go to the island southwest of the Iifa Tree. It is a long, thin island with a mountain and a forest. On this island (called Vile Island), you will fight enemies called Yan in mostly groups of three. These enemies are extremely difficult, but each group of three will give each character 28,000 EXP (more if a character is "snorted" off the screen or killed). To survive these battles, try to have all your characters equipped with Auto-Reflect, Auto-Haste, and make their Magic-Defense as high as possible. Note: If these creatures "snort" all your characters off the screen, the game will end. Make sure you have a lot of Tents, Vaccines (to counteract Virus Powder), and save between battles. Note: This is the same island to find the final friendly monster, the Friendly Yan, in the forest.

During the fight against the masked man, steal the Mage Masher. At the opera scene, keep encoring with a high score and get a few thousand Gil. After the opera ship crashes, fight in the first area that you can do so, and steal every fight for a Potion or High Potion. Use these to heal when critical. Repeat this until you gain a few levels it will pay off.
.

On Disc 4 by the Chocobo Forest, you will find one or two Mistodons that are fairly easy, but require a few attacks to kill them. Equip Shadow absorbing items. One of their attacks called Mist will heal you about 1000 to 2000 HP. If you 

Go outside of Lindblum with just Zidane and train during your first visit. You can get lots of experience when he is alone. Make sure to equip well, or you could be killed in the forests, where Bombs that have large amounts of experience are located.

 Dali: Treasure chests:
When you first visit the Village of Dali, go to the room next to the Mayor's house and climb up the ladder. You will see two treasure chests. Zidane will say he that cannot get them while the windmill is turning. The mayor is in charge of the Windmill. On Disc 3 when they return to Alexandria, you will see the Mayor from Dali in the Inn at Alexandria -- no one is taking care of the windmill in Dali. Afterwards, Zidane, Vivi, Freya, Amarant, and Eiko will go to Treno. When they arrive, before entering the card tournament, get out of Treno through south gate and return to Dali. Go to the room next to the Mayor's house and climb the ladder. The windmill is off, and you can now get the chests. One contains an Elixir.

 Defeating the Lifa Tree:
When fighting the Lifa Tree, simply cast "Life" on it and it will die instantly. It is an "undead" creature, so "Life" is essentially "Death".

At the battle of the Lifa Tree, there is an easy way to make it through this area with very little effort with the Stroupers (the little tree-like creatures). Use Soft on them. Because they are made of stone, they will become too soft to live. This trick also works at Ispen Castle against the Gargoyles and the Epithats. Use Life against Dracozombies -- Phoenix Down has no effect. You can use Life or Phoenix Down against Zombies. Against the Soulcage and the bottom of the Lifa Tree, have Eiko or Dagger cast Life upon it to win instantly. Also, do not throw away any of your weapons. They will be needed at Ispen Castle, where your strongest weapon will do the least amount of damage and vice versa. At that location, Zidane's Angel Bliss and Dagger will do the most damage.

When you battle the Lifa Tree, use Ekio or Dagger's white magic and cast Life on it.

When fighting the Soul of the Ancient Tree of Life, never use a Fire spell. If this is done, it will counter-attack your entire party with this Fire magic or do an attack that can deal over 700 HP of damage. Sometimes he may even use it two times in a row that can immediately end the game. Instead, use others spells such as Ice 2 or Bolt 2, which can do some very heavy damage on him.

 Defeating Gilzamaluke:
Start by putting a Tent on him to find out if he is affected by that Item. If not, restart and try again. If it does, he will not use magic, and about 50% of the time his attacks will miss.

 Defeating Hades:
Create a party consisting of Zidane, Garnet, Steiner, and anyone else (Amarant for example). Everyone needs to have their final weapon, with the exception of Steiner who should have at least the Ragnorok. Also have Auto-Regen/Auto-Haste on. Everyone must have armor that protects against Shadow. Hades will cast Doomsday. Have Zidane be higher than level 55, Garnet higher than level 50, and Steiner and your other character between 45 and 50. Also, prepare for all status effects. Hades will perform curse about three rounds into the battle. When this happens use Remedies or the Mini spell to get rid of the Mini status. Cure any other status effects. Hades will then use Heave and Doomdays to leave you in bad shape. Let Auto-Regen do the healing. Do not worry if you cannot get ready fast enough. Have Steiner use 5 to 6 rounds of Shock and Hades will not be able to hit you with Curse or Doomsday again. Use Dagger for healing and attack with full force. Hades will then let you Synth some of the best items. You can go back without having to fight him again.

 Defeating Ozma:
If you encountered all the spirits in Gaia and satisfied their requests go to Chocobo Aerial Garden (you will need a Gold Chocobo and a Dead Pepper). Examine the stone on the second platform and choose the third option, then the first option to fight Ozma. To defeat Ozma, put Zidane, Dagger, Quina and Eiko in your party. Have Quina use Magic Hammer three or four times to steal all Ozma's Magic Points -- from now on it cannot use any spells. Then, have Zidane and Quina attack and Dagger and Eiko heal (do not use summons, you need a large amount of MP in this battle). With some of patience (an half of an hour if you are lucky), you should defeat Ozma.

Have Zidane, Dagger, Steiner, and Quina in your party. Equip all character with armor that protects against or absorbs Shadow damage before the battle. Make sure Quina and Steiner have plenty of MP, and it is preferable that Zidane has the Long Reach ability. First, have Quina use Magic Hammer about four to five times while Steiner is using Shock. Then, if Zidane has the Long Reach ability, attack; or if he goes into Trance use Grand Lethal. Use Dagger to heal using Cura or Curaga when necessary and you should come out of the battle unhindered.

Use a party that consists of Zidane, Freya, Steiner, and EIko. Next, equip armor that dodges shadow, Zidane with the Ultima Weapon, Freya with the Dragons Hair (obtained in the Choco Quest). and Steiner with the Ragnorak (also obtained in the Choco Quest) As the battle begins, have Eiko cast Reflect on everyone and have Freya and Steiner attack with DragonCrest and Shoch, respectively. Reflect will bounce back all of Ozma's magic attacks, including the dreaded Curse. Note: The same tactic also works on Hades, Kuja, and the final Boss.

The four items you can steal from Ozma are the Elixer, Robe of Lords, Dark Matter, and the Pumice Piece. In the battle, you should steal the Pumice Piece. When you win, you will get a Dark Matter and Pumice Piece. The Dark Matter teaches Dagger the summon Odin. You can combine the two Pumice Pieces when you defeat Hades. In Memoria, in the room where Quina tries to swim, search among the coral to fight him. Hades will synth the pieces to make the Pumice, which teaches Dagger her strongest summon, Ark. Ark uses Shadow to harm its opponents.

Equip everyone with Auto-Reflect. You should also have a party consisting of Zidane, Vivi, Armarant, and Freya (the last two can differ as needed). With Auto-Reflect on, all of Ozma's attacks will bounce off and do a large amount of damage (about 9999). Keep attacking with everyone except Vivi. Have Vivi keep casting Flare at himself and it will reflect off and do 9999 damage.(Note: Auto-Reflect and Reflectx2 must be equipped.

 Defeating Steiner:
For battle one, Cinna should steal on every turn. Attack with Zidane and Blank only. For battle two, have Vivi cast Fire. Use the rest to attack him. For battle 3, yse the same strategy as battle two. Steal with Vivi and have him cast Fire.

 Defeating Trance Kuja and Necron:
A recommended party would include Zidane, Steiner, Amarant, and Dagger. Participating members should be at level 81 or above. To defeat Trance Kuja, have Dagger act as a medic for the party. All the best weapons, armor, and headgear must be acquired and equipped before the fight. Dagger has to learn Curaga by this time. Zidane, Steiner and Amarant must have the MP attack and their best weapon for this to be a quick battle. Trance Kuja has under 56,000 to 57,000 HP and his MP is 9999. Let the others concentrate on Kuja while Dagger acts as a healer. If any character is in Trance mode, just use physical attacks. Everyone's attack must damage Kuja for 9999 damage. In about four to five turns, or until the Trance meter is exhausted, Kuja should die.

 Defeating undead creatures:
When battling a creature of the undead type, use an anti-KO item and it will instantly "kill" them.

 Defeating stone creatures:
Use a Soft on stone enemies, such as Gargoyle, to instantly kill them. This trick will not work well with the spell Stona.

 Scan Bosses:
To scan Bosses, use a tent. It will restore one half of its HP. Multiply that by two to have an accurate HP total for the Boss. Note: This will work only until the middle of Disc 3, since all your enemy's HP are out of range and will just show 9999. This works if you want an accurate stealing.

 Defeating Bosses:
Have Vivi learn Reflect x 2 and Eiko use Carbunkle or Dagger use Reflect on everyone. Then have Vivi chant the strongest spell available and it will always do 9999 damage on any Boss.

Use the following if you are stuck on any Bosses from Disc 2 and onwards. Use a Dark Matter (the orb that teaches Dagger Odin) on the Boss. It is a very effective trick, as it does 9999 damage on every enemy and boss, but beware it costs a lot to buy a new one from the Auction House in Treno. This works well on the later and final bosses (Chaos Guardians, Trance-Kuja, Necron, Deathguise, Ozma, etc.)

 Gilgamish:
Once you have completed the Chocobo side quest and found all of the treasures, go to Daguerreo. Talk to the four-armed man. He should say something about an "S-Rank" and run off. Follow him and talk to him again. He should give you the S-Rank Medal, and reveal his true self (Gilgamish).

 Quadruple magic attack:
When you get a reflect ring, have the four characters you regularly have in your party with learn "Auto Reflect". When they all have it turned on, cast a reflective party spell, such as Bio or any of the elements, at yourself, This will effectively quadruple the power of the spell on a single target. However, this is only helpful for lower levels and is virtually useless if you have great spells.

 9999 damage with Atomost:
The formula For Dagger's summon Atomost is as follows:

Full Animation: (30+ Party's number of Amethysts)% of enemies HP.
Short Animation: 2/3 of Full Animation formula.

For example, if you have 70 Amethysts, it takes 100% of the enemies HP off, with a limit of 9,999. This means an enemy with 12,000 health will lose 9,999. This is useful while training against Yans, Grand Dragons, and other difficult enemies.

 Change Airship altitude:
Put the Airship on auto-pilot, then press Up or Down to change its altitude while flying to your destination.

 Early Lowell Autograph:
After seeing the Lowell Fans rant over him at his theater, go directly to the Artists House in the Theater District and talk to Lowell. He will ask you not to tell anyone, and give you an autograph (key item).

 Early Emerald:
In Cleyra as Freya, you can go into the cathedral and talk to the high priest to get the Emerald.

 Cargo ship model:
Mr.Morrid's coffees can be found at the following locations. Give all three to Mr. Morrid to get the cargo ship model (key item).

Moccha coffee: Near the entrance of south gate.
Kirman coffee: On Eiko's back porch in Madin Sari.
Burman coffee: Get to the treasure chest in the windmill in Dali Village. You will get 30,000 Gil. Check the chest again to find the Burman coffee.

 Excalibur:
Buy the Magic Fingertip from the Auction House and go to Duguerro. Give it to the old man that was looking for a book about Edions. He will give you Excalibur.

 Excalibur 2:
Get to Memoria within 12 game hours to receive the Excalibur 2. You can learn Climhazzard with this.

 Early Grand Dragon:
When you first go to Gizamaluke's Grotto on Disc 1, notice the ladder to the outside in the room with the Moogle couple. Once outside, it leads to an area with a fight involving a Grand Dragon, which definitely increases your level.

 Early Iron Sword:
While Fighting Baku in the destroyed Prima Vista, steal a Broadsword and defeat him. When you defeat the Plant Brain in Evil Forest and get Blank in you party, go to Equip on Blank and trade the stolen Broadsword for Blank's Iron Sword. Equip Steiner with it.

When fighting the plant-thing that captures Vivi, steal from it. You will eventually get an Iron Sword. When you get Steiner in your party, equip him with it.

 Early Mythril Dagger:
When Fighting the Masked Baku, Steal from him. You will eventually get the Mythril Dagger.

 Early Ruby:
When you are answering Baku, say "That's when I capture Queen Brahnne, Right" 64 times. Ruby will storm in.

 Knights of Pluto:
On Disc 3, when Bahamut and Alexander battle, Queen Garnet must deploy the Knights of Pluto and assign them to different tasks. The correct order is: Have Kohel and Blutzen gather information. Have Haagen and Weimar protect the townspeople. Have Breireicht and Laudo contact Lindblum for reinforcements. Finally, have Mullenkedheim and Dojebon prepare to fire the cannons. Beatrix and Steiner will praise you for your excellent performance and reward you with Angel Earrings.
