Just recently the VSTS Rangers shipped some important guidance packages for MOSS TFS development.
The two whitepapers are:
VSTS Rangers - SharePoint Server Custom Application Development: Document Workflow Management Project
VSTS Rangers - Using Team Foundation Server to Develop Custom SharePoint Products and Technologies Applications
The first article is created during a real world customer engagement and answers dozens of frequently asked questions and how-tos in a real world context vs. theoretical discussions. The second package addresses very common questions around setting up and using TFS features for a MOSS development project.
There's also additional guidance from P&P here: patterns & practices: SharePoint Guidance
