I'll check out Money Matters.
I recommend Jill on Money, a call-in/email show. And I recently began to listen to the Dough Roller podcast, which I learned about on Bogleheads. The title made me think it was religious, but so far, it's not. (Listen to #7, an interview with MMM. Very interesting.)
For excellent non-personal finance podcasts, I love WTF with Marc Maron, as well as the usual NPR/PRI round-up: This American Life, The Moth, Planet Money, Fresh Air, etc.
