Since my last post ages ago was about a CTP release, I'll start back up again with a post to point to the December CTP. This one is definitely an improvement over the last one, though it is clear we still have a ways to go.
You may want to check out the newsgroups for VSTS. There are a number of people there who post information based on their experiences that may make it easier for you. This post from June has all the info you need to use the newsgroups.
There are also some good weblog posts, such as Paul Murphy's post on setting up a domain controller.
The December CTP is very, very close to what we are using internally now (what Microsoft likes to call dogfooding, which is a term some people take a little too far). If you can get up and running (yes, you still need two machines), you should find it much more capable than before.
[Update] Don't forget to keep an eye out for answers to common problems on the Visual Studio Team System 2005 blog. Over the next couple of weeks, you should see FAQs and the like as was the case with the September Beta 1 Refresh CTP.
