You can definitely do it yourself! In fact, you'll have to! When it comes to binding adjustments, the only thing that will work is good old trial and error. You'll just have to play around with them until you find what works best for you.
As far as the stomp pad, if you choose to even use one, just follow the instructions. You'll want to place it near the rear binding, but give yourself a little room for future adjustments. I always centered mine in the board, but some of my friends like to have theirs toe side or heel side. I don't recommend that approach myself as you never know which way you're going to have to go off of the lift.
