How can one determining which TFS process template is being used? A few were installed and now I can't determine which one is being used by TFS.

Another one, quick & dirty and without any capability to reveal any changes you might have performed, is the following:
Right-Click on your TeamProject from within the Team Explorer and select "Team Project Process Guidance":
This should pop-up a webpage that will show you the Process Template that was used to create it.
