I removed all four door panels this past weekend, and the wood trim pieces. I smeared molybendum disulfide wheel bearing grease over the contact parts of the wood trim and the plastic on the panels. This is black stuff, so it doesn't show on the blue plastic and wipes off nicely with a rag. I tightened all the nuts down good and no more creaking!

I now notice that there is some squalking from the rear door areas, probably from the door panel bottoms as described, so now it's on to the solution for that.

Oh yes, must mention that I removed and reinstalled the driver door panel 4 times, twice to test the solution-on-trim, once because I forgot to push the wires for the lower lights through the hole in the panel back, and once more because 1 panel clip (lower right corner) didn't engage properly. Check first before putting the door handle/seat switch escutcheon plates on and bolting in the armrest! PITA.
