Congrats on the new purchase (early Christmas present?). Bob is right about the 750 bushings and the LaJolla sway bar, go for it, esp. if you get the 16" wheels. When I got my 16"ers, it was like a new car, and the bushings have made it even better (the sway bar is next on my list, maybe Santa will bring it?). When I got my 16" wheels, I went to Discount Tire and got the M5 lookalikes. Cost was about $1200 with a set of Yokohamas. Check out their website (www.dsicounttire.com) or Tire Rack (www.tirerack.com). If you want the wheels used, someone always seems to have a set for sale here or on the E32 board, or check the wheel board. Good luck!
