Check out podcasts--Dusty White has an extensive catalog (just google dusty white tarot podcast, there's a link for the podomatic website). Biddy Tarot just started one, I haven't had time to check it out but it's probably good. I have listened to some others (Menage a Tarot, Beyond Worlds), but I think Dusty White & Biddy will be more focused on learning tarot for the beginner; anyway in my limited listening to all of them those have provided me with more "useful" information.
