I have poly mounts on my tan Jeep. While the body mounts don't bother me, when I put in the motor and transmission mounts the vibrations are terrible. Rubber anywhere is going to be smoother/softer than poly, just won't last quite as long. That said, it's not THAT hard to replace this stuff, and given that it seems to last 20+ years, when I replace the stuff on my green Jeep I'll probably go rubber.
Original console is a good thing to have. You could get a retrosound head unit which will fit without modification. The head unit will control a CD changer, and it has an AUX hookup. Something else to consider.
