For a limited time, you can sign up for some online courses from Microsoft covering various details of Visual Studio 2005. It looks like you get a year's subscription to the course, though most of them take between 2 and 4 hours to complete.
You can see their other courses here (the special offers are listed at the bottom).
I've never taken one, but since they're free I might. I'm typically underwhelmed with online courses but these might be pretty good.
