Corbin actually did a write up not too long ago that details how to fix the door locks.

I can't get my links to work correctly, so just copy and paste this into your browser.

I've never torn apart the side mirrors. My car is white with black mirrors and I have always been lucky enough to find black ones in the junk yard since they are fairly common. If I did have to paint a set, I would probably try just taping off the mirrors first, but I tend to break things when I take them apart, so I avoid it when I can.
