one additional thing that's nifty is to get rid of the spin wheel "click." to do this, once it's guts are exposed, take off the wheel mount, remove the wheel from the mount, and stick a small flat head screw driver in the open side to pry out the spinning part. a small ball bearing will fall out - that's what creates the friction and the "click" when you spin the wheel. now put everything back together and presto! smooth wheeling!
