the door handles either pop off or have an allen bolt holding them in place. The window cranks need a window crank tool (like $5 at an auto store). as for the panels themselves, I just carefully pryed the first few out with a screwdriver (along the bottom so it wasn't noticable if i screwed up). After I could get my hand in there, I just carefully pulled with my hand.
And for putting them back in, get all the clips lined up then just push them into place with your hand.
