Knowing assembly (MIPS in this case) and the architecture you're exploiting is also a must besides having good C knowledge. Also to get grip of PSP exploiting, I suggest you get an already known to be exploitable game (preferably one with stack overflow, since it's the easiest one) and exploit it all by yourself.
PS: if you're going to learn programming, do it on a PC, not on PSP. It's a waste of time.
