Hello Brian Mains,
Unfortunately if you would like to switch templates on existing projects, it is simply not possible in TFS without starting from scratch.
Another option however is to change the parts of your existing TFS projects. For example, changing the definitions of work items from CMMI, for example, to Agile, import the Agile reports, etc. Here's an MSDN article
that explains what that will entail.
Hopefully that helps you out and please, feel free to leave some feedback on TeamPulse after you have tried it out, we are happy to hear it!
