On mine the dash, door and 'dogleg' or rear quarter were steel... very heavy gauge steel. The 3 rear cappings were soft aluminum. Check with a magnet if you're unsure of what's under there.
The steel pieces were a tight fit, I took a short length of wood (1x2 or a dowel or such) and put it against the edge of the piece and used a hammer on the wood to tap the capping up & off. Go slow, work in several spots. If you were not repainting then you would have confined this to the inside edge.
I think the steel pieces are usually covered in leather and will probably be an even tighter fit going back on. The aluminum pieces are typically vinyl-covered and are easily shaped and fitted.
Screw removal is as noted -- basically the door & rear quarter caps are the last interior bits removed and the first ones to go back on.
