Secrets of Podcasting, Second Edition: Audio Blogging for the Masses (2nd Edition)
Until I get up and running this was kinda academic, not a bad look at podcasting, however the edition I had was from 2006 and things change a lot in computers in 4 years. It's a good basic introduction to the start of podcasts and the basics of how to do it. Suggesting at least a vague scripting so that you have something to work with if you run out of ideas and a pop-filter are two that I'm going to have to implement myself. It's written in a fairly accessible style and doesn't talk down to you.
