When your local REI does again offer in-store bike repair/maintenance classes, I highly recommend you take them. If you are an REI member, you will receive a discount on the cost. In addition to learning about bike maintenance in general, you will learn more about the specifics of your bike as you put it up on the stand and work on it. The classes are also a great way to get to know your local REI bike techs as well as other cyclists.
Once you take the REI classes, look for a Park Tool Bike Class at a bike shop in your area. It is longer, more extensive, and overall costs more than the REI classes (but less for the total number of classes) and will really ramp up your repair skills and teach you about your bike.
