Microsoft XNA. So where do I start?

Apparently, the only consensus is that Professional XNA Game Programming is a miserable book. Some recommend Microsoft XNA Game Studio Creators Guide. Regardless, I'm popping over to the nearest Borders and using this coupon! Or you can just look at the support pages and code dumps of these books.

While you're searching for a book, you can still get started with XNA Game Studio Express and the XNA MSDN Library.

Here is an article by CoDe Magazine, "Introducing XNA Game Studio Express". Unfortunately, since it's not two months old yet, I can't read it but, George W. Clingerman, the article's author, has a excellent website, complete with simple tutorials.

Some nice tile engine tutorials at XNA Resource.
