On the book front, I'd also recommend Foundations of Mechanical Accuracy by Wayne R. Moore. It's a great treatise on how you can measure things like one millionth of an inch, and has lots of incredible pictures.

Looks good, but it's out of print.

There are also a few pdf copies floating around that are acceptable quality.
