If you really want to understand them the BEST book is by Forest Mims the 3rd called Timer, Op Amp & Optoelectronic Circuits & Projects, it has detailed schematics and explanations for everthing you would want to know.

This is possibly the ultimate book for you:
http://www.amazon.co.uk/Integrated-Circuit-555-Projects-BP/dp/0859340473/ref=sr_1_1/203-6935087-2798348?ie=UTF8&s=books&qid=1173116172&sr=1-1
It reads like an old uncle who smells of old spice.
