Door skin problems

I have a little door problem on my Cavalier. When I removed my bodykit to have my car repainted, I noticed that my driver side door is busted by rust, so I was able to find another door in perfect shape from a 95' Z22.

The problem is that my car was made with manual windows, and the door I bought have everything set for electric windows.

I want to keep my windows manual to be less problem, but removing the motor and putting the window crank in the new door in kinda hard because there is not too much space to work with, so I was planning to remove the door skin, so I have more place to work with.

But how do I put back the door skin on my new door without damaging it?

Also there is some kind of rivet holding the window motor, is the a way to remove them without damaging them, or should I just drill trough the old one and try to either use normal rivet to put the manual crank on the door, or try to buy a replacement for the original ones?
