I haven't removed a 123 door skin for awhile and am concerned that I may be thinking of my 124 . . . but in general, the door skins are held on by plastic hooks so you lift up rather than pull out.

The chrome trim at the latch mechanism (2 Phillips screws), door lock pull knob, inside door handle (similar to old VW bug), possibly ashtray, all have to come off first.
