Chris-
RIDE A SKATEBOARD FIRST
Skate down the street, get a feel for carving and the movement of turning and swaying back and forth. Its the exact same motion that you'll be doing on the snowboard. Trust me, it comes a lot easier when you have an idea of what is "supposed" to be happening. I was boarding without problems after about an hour of riding, it was a cake walk.
Oh yeah, and strap a pillow to your ass
