If you can do your own work, I recommend looking for used seats in good condition and just replacing the whole seat. You'll get better results that way, when compared to an aftermarket seat cover. You could even switch to a leather interior if you like.
Same thing for fixing the dash. I've seen good results with Eclipse dash covers; Widgmaster's looks very nice. But most of the ones I've seen look amateur. The Coverlay cover runs $300, and for that you can buy a used OEM dash with all the trim pieces. True, you'd have to install the dash and it's a moderately difficulty repair. (More difficult than say brake pad replacement, but not as involved as spark plug replacement on the V6.) But the results are, well, OEM.
The 3G Facebook group is a more active site and better for finding people parting out their cars or recovering parts from junkyards. There's a couple dashes for sale there now. But FB is terrible for technical advice on how to troubleshoot or fix things, and there's no historical information like there is here. It's easy here to find 20+ years of peoples' experience fixing a P0300 or whatever. Anyway, I think there's a role for both places.
