Yeah, I'm a Shimano *****, but I'll second that -- Shimano components you replace, Campys just get repaired.

I was going to recommend Bicycling's Guide to Bicycle Maintenance, but it's more of a book for newbies to bicycle repair (like me) than for more experienced types. But I'll throw it out there, anyways.

There's a more comprehensive guide, but the name escapes me...
