Welcome to the forum, and to PrPro CS 5.5.
By "templates," I assume that you are referring to what is called a Sequence Preset in PrPro. Those are built in, plus, you can create your own, with Custom.
After the Help file, I would look over the great material in the FAQ Section. Todd Kopriva has created a lot of great tutorials, and they will help you get up to speed quickly.
Hope that this helps,
