Whoops, submitted before I was done. The ASP.NET MVC site has tons of videos/screencast on getting started with ASP.NET MVC. Definitely watch the Scott Hanselman ones first.
Edit
The Rob Conery screencasts that @David provided are provided on the ASP.NET MVC site also, under videos. That would constitute one spot to get those resources and also the ones the ASP.NET MVC team put out.
One note on any resource you use. You could run into functionality that is no longer available in the framework due to it being in development. If you use the resources provided that you already found along with the tutorials, you will find the replacements or how to get around it.
