1.- The first one, you will get it after use a lot of times Tidus's Overdrives, around 80 successfully overdrives I think, and the second is first Blitzball Tournament Price, so you need to play a little in Blitzball, I suggest use Jecht Shot every time you can
2.- Don Tonberry and the old Don Tonberry trick
3.- The boxes-like enemies in Omega Ruins, I forgot the monster's name
4.- Defeat high level monster, maybe someone else can help you with this, because I have duck's memory and when I noticed, I already have some LV. 4 keys
5.- Dark Aeons, some enemies, and the strongest enemy ever in a FF series
6.- I haven't battle Dark Aeons, I have NTSC version T.T, but you can see this strategy at FF X's section at Eyes On Final Fantasy , at the section named Dark Aeons I think

Well, I hope this can help you a little, good luck
