Hi, guys. I'm trying to complete FFX-2 by getting FFX-2 perfect ending. I need a lot of help from you guys, here are some questions:

1. Did I lose percentage if I didn't get 650 points in Gunner Gauntlet? (the highest I get is 624)
2. Do I have to get all the GG and dressphere for 100%?
3. Is Via Infinito needed for 100%?
4. Where is the best place to catch chocobos?

This one is just for game completion:

1. Can I still calliberate the towers in Thunder Plains in Chapter 5?
2. Where is the best place to train, preferably the best place to receive AP and EXP other than Via Infinito?
3. I forgeot to oversoul all the monster in Kilika back in Chapter 1, how do I oversoul them? (I really need The End GG)

Hope to get help soon.
I stick to this thread and ask question from time to time

EDIT: To Mod, Close this if need.
