It is hard to remove that door trim without bending it. I destroyed the first set, but learned how to get it off without damage. I use a 1" plastic putty knife. Insert it at the curved end of the upper trim and just slide it along the door. It lifts and removes the trim without bending it. When reinstalling after it is snapped in place a soft faced mallet can be used to roll the edge down tight to the door frame.
The quarter window trim I have never removed so I can not help with that.
