Kingdom Hearts II Need help finding 8 materials + Level up help

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:

English:

[1st Collumn]..........[2nd Collumn]
Mythril Gem..........Mythril Crystal
??????..........??????
?????..........?????
[kanji]ragi Shard..........???????
??????..........??????
[skip a few]

Orichal

Japanese
ミスリルのかけら。。。。。ミスリルの結晶
？？？？？？。。。。。？？？？？？
？？？？？。。。。。？？？？？
｛漢字｝らぎのかけら。。。。。？？？？？？？
？？？？？？。。。。。？？？？？？
[skip a few]
？？？？？
オリハル


Also, I need to find a good place to level up (I'm currently Lv. 75) without killing myself.

 

World that Never was is the best place (playing final mix +) But in the normal game the best place to train is on the peak where you fought scar in the pride lands.

 

Have you got the materials from the XIII mushrooms?

 

Unfortunately, this thread is now useless, as I go the materials before anyone posted. Sorry...
