Atlas bits: http://atlas.asp.net
Free copies of Visual Studio Web Developer were available, you can get it (free) here: http://msdn.microsoft.com/vstudio/express
(note: when you register you get a bunch of extra stuff -- access to Corbis images, free hosting, etc. -- makes it easy to try it out).

The site demoed can be viewed online at http://asyncpostback.com and there is a link to download the entire sample site as well

Also, the link at http://www.learn2asp.net is a site with content for PHP developers (and CF/JSP) to get a better understanding of ASP.NET. Take three web casts and get a package of free stuff.
