go do lesson...have fun...ride as much as possible this season...this will give some ideas and references for discussions on gear and technique.
over the off season, watch vids of learnin, read, and watch for gear. consider SA vids and/or snomie/Jed
Buy boots first and read and understand this
if you get board bindings can go used, get intermediate stuff
then go to back yard with gear on and hop and jump around
do squats, balance stuff...watch more learnin vids
