Don't think the M5 clutch is compatible with the 6-spd flywheel, you'll need to check with UUC about that. Of the options that I know will work, go with the performance organic. Avoid anything multi-puck on a daily street driven car.
As for engine mounts, the ONLY aftermarket mounts I can recommend for street duty are the BimmerWorld solid rubber mounts. They will add a little bit of noise and vibration over the stock fluid filled mounts so if that might bother you, just stick with stock. There are a couple of reviews of these and the near identical (except in price) Group N mounts around here that you can search out. For transmission mounts, I like the black neoprene UUC street mounts paired with the enforcer cups. I run the BW motor mounts with UUC transmission mounts and enforcers and they work very well together.
