Nice presentation, Thom. I'd add one thing, though. Because the iPod has total market domination for MP3 devices, getting into iTunes is essential. iTunes requires certain specification tags to be included in your podcast feed. I use Feedburner's podcasting options to automatically insert these iTunes tags.
The PodPress plugin also inserts the iTunes specifications, but since PodPress sometimes breaks with new releases of WordPress, I don't recommend PodPress. I wasn't always an iPod user, but since switching from the iRiver to the iPod Nano last month, I'm a total convert. iPods are the way to go.
