I worked with Microsoft’s Eric Charran on a previous engagement, and was pleasantly surprised to see a very helpful article he put together recently.

Summary:
Learn to properly conduct team-environment development of Microsoft Office SharePoint Server 2007 sites and assemblies (Web Parts, site templates, custom list templates), as well as develop Microsoft Office SharePoint Designer artifacts (master pages, workflows, CSS sheets). (13 printed pages)
Also, some updates on virtualization releases from Microsoft might be of interest to anyone making use of Eric’s team-development strategies.
