Not to say that a course wouldn't do you some good, but if you are already proficient with tools you might appreciate Lennard Zinn's book, Zinn and the Art of _______________ Bike Repair. (The blank is there because he has a few different books for road bikes, mountain bikes, etc.)

I took a course at Barnett Bicycle Institute in Colorado Springs a few summers back, but before that I used the Zinn books for years with good results.
