I will just add that don't get bottom bracket tools until you're sure what kind you have on your bike. In general vintage bikes can be worked on with the same tools, but newer bikes require special tools for bottom bracket removal. Likewise for cassettes and free wheels.

Also Zinn and the Art of Road Bike Maintenance is my favorite repair how-to book. Having a book works better IMO than walking back and forth to the computer or putting your greasy fingers in your tablet.
