I did the front window strips today - I wanted to wait for a warm day just to make things easier. You were all right, it was easy.
The passenger side one split in half and a piece fell back inside the door, but I managed to hook it with a piece of cable and pull it out.
I had a quick look at the rear window ones but I couldn't see any obvious screws so I thought I would check with you guys what the process is for the rear window strips.
