The Microsoft Patterns and Practices team, in concert with the TFS team and a panel of customer reviewer has just released a terrific document on TFS Best Practices.  This is distinct from the TFS help on MSDN in the sense that it is not "How-to" guidance but is conceptual information and recommendations for how to use TFS to fit your development process.

The release is in "Beta" now and we are taking feedback for further improvements.  Please look it over and give us any feedback you have.  It's pretty long (hundreds of pages) but it's organized well and you can go straight to the guidance you need.
