Paul,
I've got a slightly older version of the Zinn road bike book (the only obvious omission is the newer cranksets with integrated BB's), it's a bit short on diagrams/pictures for the totally uninitiated but it did me well for learning some key tasks (removing cranks/BB, threaded h/set and aheadset adjustment, gear adjustment) but to be honest I could probably have found it all on line. You're welcome to it if you like as I think I've got a handle on it all now, just send me your address.
