Once you get the axis mapped, fly around offline and make sure that the hats and buttons you will use a lot, like views, vox, and flaps, are easy to reach.
You'll want an "up" modifier for the view hat. You can also map 2 hats, one on the stick and one on the throttle, to combine views instead of hunting for the corner positions on an 8 way hat. You could use front, back, left, right on the stick and up, down, front, back, on the throttle. That lets you check 6 with either hand.
You don't need to map all your buttons right away. It's better to take some time and figure out what is more efficient for you. Buttons like gear for example, which you typically push twice per flight aren't as important as the clipboard which you may toggle several times.
