for boots: go to a store and try on as many pairs of boots as you can, get the ones that are the most comfortable. As long as they are from one of the name brands they will be quality.
Bindings- get some medium stiffness bindings, burton/ride/k2/rome all made good bindings. make sure they fit the boots you buy.
Board- I think the ride machete is a really good all around board that is very durable, i demoed one a few years ago and really liked it. Next the T1, solid board, flat base is more stable than the all rocker boards.
Dude, suckin at somethin' is just the first step to bein' sorta good at somethin'
