Kingdom Hearts II Need help finding 8 materials+Leveling up

I am going for the Ultima Weapon to fight Terra. However, I am missing 8 materials for the Synthesis.

Here's a diagram of a section of the "そざい (raw materials)" page:

Also, I need to find a good place to level up (I'm currently Lv. 72) without killing myself.
