I saw this great posting on J.D. Meir Blog and wanted to point you to it as well. It’s a useful guide that helps consolidate some information and provides additional content and resources.

• Shows you Windows Phone content and where to look
• Provides an index of the main content collections (Code Samples, How Tos, Videos, and Training)

Download the Windows Phone Developer Guidance Map v2.0 here

I’ve also copied from JD’s blog a list of content for easy reference:
