Please help...this is too big for me

Hi i got a tutorial from Senocular about an infinite gallery resize with shadow , but i am having a lot of problems trying to fit my needs:
I would like to have the infinite menu with the thumbs embedded into the movie(instead of loaded externally), and i would like to add a prev and next button.
Please help i have very little knowledge of AS and i don’t have a clue what to do.
I am using flash mx.
Here’s the fla
