I think that's a great starter set you got. That Aviar is probably your putter.
Tip #1: have fun. Sounds obvious, but still, don't get bogged down in what your score is right away.
Umm, after that, I'm not sure how general or specific to be. You'll want to get a feel for what your discs do for you, distance- and flightpath-wise. You might find yourself gravitating towards one main disc that always seems to go where you want it to, that's normal I think. I think heading out to Green Lakes when hopefully it's empty enough where you could throw the Cheetah, Shark, and Eagle every shot except putting. I get my best practice on approach shots still aiming at trees in a large park-like setting behind my apartment complex.
If you're feeling confident enough to start seeing how far you can drive, Jamesville Beach is long and open. When you get those approach shots feeling good, Oxbow is more technical. Clay and Emerson I don't know enough about yet.
Well, that's it for now. Write in with more questions and more experienced people can answer. Look for us on the courses too, happy to group up.
