Doug Turnure, Todd Fine, Mark Dunn and Brian Hitney have produced a series of training videos covering the 4 core parts of .NET 3.0 and released them to the world on the .NET University web site.
If you haven't previously checked out .NET University you really should. We hosted one in Charleston last year around this time and it proved quite popular.
Get the video's free by visiting their course content area here: http://www.dotnet-u.com/coursematerials.aspx - and while you are there pick up some slide decks and hands on labs covering the material too!
