I don't want to download and install SP1 for Team Foundation server 2008 if I don't need to. But I'm not sure how to determine what version our server is currently running?

A:
If you have Visual Studio Team Explorer 2008 SP1 installed on your client machine, then look in source control explorer to see if you have anything populated in the Last Check-in Date column. If there is data the server is SP1, if there isn't then it is pre TFS2008 SP1. (See my blog post where I talk about this feature)
Alternatively if you can log into the machine, take a look at ProgramFiles\Microsoft Visual Studio 2008 Team Foundation Server\Web Services\Services\bin\Microsoft.TeamFoundation.dll. SP1 has a version of 9.0.30428.1
Enjoy,
Martin.
