When you get warped back 2000 years, and you can't find a way out (because there is none), go to the floor where you fight Tiamat. You should fight some purple worm-like monsters. Keep fighting them until you get an item called emergency exit. Use it and you will teleport out of the Shrine!

I've found out that the easiest way to beat Garland is to fight enough battles so that you have enough gil to buy all of the armor for everybody, that way when he hits you, he only does 1 or 2 damage to you. It will also help if you buy the best weapons for everybody so you can defeat him quicker.
