Sounds like you are on the right track. Any changes you make, they should be small increments until you learn and fully understand exactly how they effect the truck.
Another "don't".... don't mess with the scalers yet. It's going to be tempting, but wait until you get really good at your tuning.
Some "do's".... ask questions, lots of them. Even if you think it might be a dumb question, ask it anyway. I've noticed that the guys who tune and post here on this forum are some of the nicest and most helpful bunch you'll ever find. Also do plan to spend lots of time. Tuning isn't something that happens overnight.
Enjoy, and welcome to the "club".
