don't take my words as gospel but try not to get a burton carving board, the technology has gotten much better sonce their time. f2, nidecker, volkl, are some boards you may find in a respectable price range, If you can afford a coiler I would highly reccomend them, just go to coiler.com abd check out the specs of the board before you buy, because they are weight specific. Donek, prior are also great boards.
burton bindings are cool because they are cheap, there are some on ebay right now, i think. trench diggers can be found for around 100 bucks or so, there are others, just know that bindings with plastic are much more flexible than all aluminum.
boots are important, you should try to find a pair with 4 buckles or more, and hopefully a booster strap, thats the strap on the highest point on the boot. hope that helps
