Haha alright well.
What size boot do you wear? Also it's not your height that matters for the length of the board as the kiddies behind the rental booth would make you believe it's actually your weight, so how much do you weight?
I'd say start off with some '09 Burton Missions for your bindings. Good solid over all binding I have them I think mine are '08s but they are still working perfectly no problems here. You can get them real cheap somewhere online right now probably. Most of last seasons gear will be on sale right now 40%+ off.
BUT, you want to pick out some comfortable boots first before anything else. If you know of a local shop go in with no thought or option of buying ANYTHING that day. Make sure you don't get suckered into buying anything. Just simply go in to try out some boot feels. Again look at last seasons stuff. Becareful they will be like sharks trying to get rid of their old stuff. Do not let them pressure you at all. If they ask if you want to buy it just say not today i'll be back another day. LEAVE NOW! (don't look around, just run for the nearest exit!) LOL
That will be a good start though.
