It's a start and congratulations on your entry into the ranks of those who are getting to use TG2TP at its beginning stages.
If I were you and I was beginning again, I would start on one Terrain or Shader subject to learn it. There are some good tutorials in the Documentation section on this site and you could walk through those, mastering each tutorial as you go, and then create something. I would bet that will be as exciting as it gets. It is for me.
