Yep, there is a lot to learn, but it sounds like you are taking that seriously, so that's good. When I was first learning, I just flew in a big open field for several hours getting used to the controls, the gimbal, etc. And I watched a LOT of YouTube videos - those were indispensable when first learning how to fly, use the app, and get good footage.
Most important things to remember are 1) wait for strong GPS lock before taking off, 2) make sure your Return to Home settings are appropriate (RTH altitude, etc), and 3) don't fly under anything that could cause your Air to fly up to Return to Home altitude. Stay within line of sight (especially when learning), and concentrate more on flying at first than getting good footage (that can come later after you are a more experienced pilot).
Happy flying!
