TSL,
My self-help program this spring is to take 8 hours of Park Tool bicycle maintenance classes. The REI Flagship store in Seattle is offering the full Park Tool School curriculum over two days (next weekend) for $125. It's geared toward people who are not maintenance beginners but who are not yet advanced.
It's like tai chi, only you have an Allen wrench in your left hand and a third-hand tool in your right...the only politics involved are Campy vs. Shimano.
You may already be beyond this....
