1990 Chevy Lumina APV - need help with door handles/locks

I just bought a 1990 Chevy Lumina APV, and naturally the passenger side door handle and the sliding door handle is broken as well. Also, the power locks don't seem to work, and the window on the passenger side does not move at all (the window on the driver side goes down about 5 inches).

I bought the needed parts (knock wood) on eBay, and I looked in the online guide that is linked at the top of the forum, however I did not see any info on how to take the doors apart, etc.. Does anyone have any good info on replacing the door handles, as well as the motor and door lock actuator and/or door switches?
