Easy
It's not hard. If your map pocket is still intact, there's screws around it's perimeter that hold it on. Then unscrew the armrest...don't pull it off just yet though. Unplug the wires for the mirrors, then carefully TWIST vertically about 90 degrees to disengage the handhold from the door. Unscrew the plastic door release lever backplate. Then, take a large flat-blade screwdriver or equivalent and *pop* the door panel plastic rivet things from the door. These are around the perimeter of the panel. Don't be scared, just pop'em. Once you have the panel loose, and the mirror triangular piece has been removed, push UP on the panel to remove from the glass.
You'll notice the plastic liner covering the door. This is important to keep intact, as it keeps water from getting inside your car. If you cut it open, tape it back up somehow.
This is off the top of my head. I probably forgot a step, but nothing major. Why are you removing the panel?
