yes u get her items back.

though i would advise u to train her.there is a tough boss later, infact its the hardest boss on disc 1 and Aeris must be in your party. so train her, or at least get her lv2 limit fury brand(or maybe the lv3 limit that makes u invulnerable).

i say this because u r a pretty low level, and i would definitly consider Bottomsawell an easy boss.

i dont really know what to tell u as every time i just like used bolt2/choco mog attacks and it died pretty fast. i guess haste, quick phoenix down use, and limit breaks would be very useful. try looking at gamefaqs 4 a guide if u still cant win.

EDIT-i hope u dont feel i,m insulting u, i,m not! sorry if i came across that way.
