I did the black contrast in the interior on a '70 Dart I used to own and really liked the result, left the white vinyl top off and painted it all F8 green, it's a personal preference, too much of any color doesn't work for me. I would think loop for the carpet, but may depend on trim level,(low, medium, or high), as determined by the second character in the VIN code. I would suggest looking for used parts on this site among others if you wish to stay on a budget. New reproduction parts are expensive, and often not very good quality, lots of members have had bad experiences with repops. Rebuilding the booster should probably be handled by a shop that specializes in them, I have no experience in them myself. Legendary has upholstery for most cars, and a good reputation. Your brightwork can be restored as long as it's not rusted, dents can be removed and polishing will return the shine.
Nice car, keep us posted, and BTW we love lots of pictures!
