Scott the carpet looks really good. I got some samples from the link you sent me and they look really good as well. I got 4 samples from black to silver...now to decide..lol.
Classic Parts does a really good job about replacing things..I had a couple of things I ordered that were toast when I got them...called and just like you they sent replacements out quickly.
As far as the door weatherstripping I purchased mine from Precision

these are the push on type which I like. I tried it on the passenger side and they worked pretty good....a lil snug but not real tight...may be an option for you if you don't like the ones you got.
BTW what are you doing for speakers?
