I recently went to one of the asp.net MVC3 web camps in Redmond, WA. You can access all their presentation slides , demos and labs here. I found it pretty useful as an introduction to MVC3. There are beginner and intermediate labs. Hope this helps!

Of course, as they are free, you can check the schedule to see if there might be one near you. Especially useful for beginners and if you have specific questions, they had a lot of their team on hand to answer questions.
