Great. I just got all my sound deadening stuff shipped last week. Thanks for the tips.

I did not do anything to replace the moisture barrier, because when I opened the door I did not see any evidence of water having ever leaked in there. It was all clean and dry. - After 62,000 miles with harsh winter weather!

I also didn't do anything with the plastic door panel itself, other than replacing broken clips/fasteners with new ones (box of 30 cost $15 in a local upholstery store). The plastic didn't seem to vibrate when I had sound coming out of the door speaker.
