Re: rear main seal
I doubt the two are related but it does sound like a bad trans mount. Real easy to swap and you can get them almost anywhere. I wouldn't recommend polyurethane unless you want to feel every single bit of driveline vibration.

Re: rear main seal
Really varies from car to car. The M6 doesn't seem to be as unforgiving with a poly trans mount. I had the ES poly under my original T56 (a little "buzz" from the shifter) and then under the TH400 and now under the TH400 + Gear Vendors O/D, and never found the noise or vibration to be a problem.
