Thanks to Dick Baker, one of the attendees at my recent Silverlight session in London, for sending me a link to some VS 2008 (and more) training that's available on the Microsoft Download Center at: Visual Studio 2008 and .NET Framework 3.5 Training Kit
It's packed full of useful stuff - much of which I haven't seen. It's a big download (120MB) but worth it. There's presentations, demos and labs stuffed in there. I've included screenshots of the relevant content folders so you can get a better idea of what's in there.
