The documentation/tutorials that come with Visual Interdev are a great place to start.
Those can be accessed through technet as well.
Assuming you're targetting a fairly modern platform and have some working knowledge of programming, I'd suggest O'Reilly's book (Current edition is Learning ASP.NET. It's HUGE for an ORA programming book). Combine that with some online ASP tutorials and you'll probably be OK.
I'd suggest avoiding things like "Learn ASP in 24 hours" or whatever. Those are lousy for refrence purposes and don't take you far enough down the path.
Microsoft books are dry as hell,and technically accurate.
Pearson/Que/Sams/New Riders are books by commitee. Chapters tend to be held from one published title to the next, and the quality of the material is disjointed depending on the author.
Sybex has the same problem, but it's a different company.
Addison-Wesley seems to usually have a good balance. There are some really well-respected AW computer titles.
Another option would be to look into PHP. PHP fills the same niche and is pretty easy to learn.
