Bindings such as the customs, freestyle, and missions are user pretty good for those just starting out, plus they're fairly cheap (sunandski.com has freestye bindings for 89$$)
I was going to recommend the freestyle bindings for something cheap to start with, especially since you only go a few times a year. As for the board, I was never a big fan of the T1, but it's not terrible. For something cheap, and fun to throw around on a smaller mountain like you describe I recommend this.
