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
