Learning more about Team System

We recently received the following question from someone on our team:

I have a customer who would like to clarify what exactly he’ll need to purchase in order to enable source control/bug tracking/testing scenarios within Visual Studio/Team Foundation Server. ... Ideally I’d be able to point him to a whitepaper or website that describes these scenarios and exactly what needs to be purchased so he can use those materials to justify spending the money.

Here are a couple links that might be helpful:

We don’t have a whitepaper that does exactly what the customer was asking for although our presales site will soon change to become this.
