The centre panel should jus pop off with the 4 nuts off.
As for the top outside door trim roll down the windows to take the pressure off the trim.
I think there is a screw at the door latch end of the door on the rubber seal. It should jus pop up but I cant remember is the mirror in the way.. Unfortunately Im not near a door at the minute.
Just a tip. If there is any stainless aluminum showing through on the trim give it a roughin up with a scotch pad and prime before paint.
Have seen a lot of them sprayed and shortly start peeling again..
Best of luck
