I am not a designer and I'm not sure about how to choose fonts for any particular usage, but I've enjoyed a little book by Robin Williams, "The Non-Designer's Design Book: Design and Typographic Principles for the Visual Novice". The author lays out four basic principles: Contrast, Repetition, Alignment and Proximity (CRAP - I love it; it's very memorable). The idea is that if you follow these principles, regardless of the types/fonts you choose, you'll have a better looking, easier to read document.
