Roy Osherove maintains a great blog on .NET unit testing, agile development, and VS Team System. This weekend he posted a pointer to a free video of his "Implementing Continuous Integration: With and Without Team System" presentation at TechEd Europe last month.
Continuous Integration is definitely a best practice I'd recommend implementing for any team project. Watch Roy's presentation to learn more about it and how you can implement it today.
Hope this helps,
Scott
