Noobie that need help

Hi

I just got a psp slim and a 2gb memory stick not too long ago, so i haven't mod it

My question are:
1. Can it be install on a psp slim
2. Can it convert rmvb, rmv video types into the psp?
3. how much does the file get shrink when it is convert to the psp?

thanks
cheers
