Here's a couple good sites for asp.net tutorials that I've found useful.

If you don't like the ASP.NET web matrix IDE, I would recommend using Visual Studio.NET, one cool thing with .NET is the code behind feature....where basically the application's code and the actual web page(s)/web forms are seperate. If you have previous VB experience this will certainly come in handy.....good luck with learning .NET
