Quick tip - if you're trying to get up to speed on Visual Studio Team System, MS has a great little lab available to let you take a self-paced guided tour on a live, hosted Team System box. Really a nice way to see the sights. I've found this is also helpful when introducing new team members to VSTS -- "Go take the 30-min tour, and then we'll talk about how we use VSTS on our project."
