I don't know of any tutorials on how to make enhanced podcasts. I figured it out just by using GarageBand which now comes with some easy to use podcast tools. Unfortunately if you're on a PC, I'm pretty clueless. I don't know if Apple is using anything proprietary for the enhanced podcasts or not. Wish I could help more.

Glad you liked the podcast by the way. I hope to do more band interviews in the future. Although, I want them to be more like the band has taken over Shifted Sound and have them introduce their favorite independent bands along with their music. Obviously BA was a little too busy on their own music to be introduce other bands'.
