Tektronix has a very complete guide to scope usage on their site. For tube amp specifics, I'd recommend Morgan Jones's "Building Valve Amplifiers" which has a pretty thorough examination of scopes and tube circuit troubleshooting.

When I used to use a scope that itself was built around valves, I appreciated the vertical 50V/div. Nowadays I make do with 5V/div. An attenuating probe for me is essential.

Take a look at "Oscilloscope Techniques" (especially chapter 7) on by book page: http://www.pmillett.com/technical_books_online.htm
