I'm stuck and need some questions answered

[Hambone]

I got the DS version yesterday for Christmas and I'm fixing to go fight Hein...again. Here are some questions that I have about this and other features on the game.

1. What level should I be on right now?

2. Who should have which job right now in order to beat him the easiest?

3. which jobs should I be using at the very end of the game? I plan on having a knight, sage, dragoon, and black belt. I think I'm going too offensive.

4. Is getting onion knight worth it and is it really recommended?

5. What level should I be on at the end when I fight Cloud of Darkness?

6. I really don't want a summoner. Is it really a necessity?

7. How do you think Ingus should be? A mage or fighter. I see him more as a fighter.

I'll think of more questions later.
