There are 100,000 good ability combinations in this game, so it's going to be hard to say which is best and everyone will have their "super-character" combination that they will swear by. Just remember that new weapons for advanced classes don't come along until later in the story. "Gained JP up" from the Squire is a great skill as it allows you to learn abilities faster. It's always a good idea to learn "Move +1" from the Squire or "Move +2" from the Theif. "Move +3 is learned from the Bard, but that's a long way off for you to get at the beginning of the game without a lot of fighting. Hope this helps.

And to finish, pick what you want. That's the great part about htis game is that you can play it with different combinations any time. There are only a few hard battles in the game and you won't get to any of those until the end of Chapter 2 and Chapter 3, so experiment and enjoy!
