make sure you try on boots in the store, brand isn't important really. make sure they fit, becuase boots that don't fit can ruin a whole day. look at the "boot fitting guide" sticky to see how they should feel.
for a board just look at some nice brands in the price range you want. it sounds like you would proabably want an all mountain board. i have a nitro magnum and i really like it. gnu, rome, nitro, buton, never summer, atomic, forum, etc. are all good brands.
for bindings i hear a lot of people recommend ride, rome, and burton. just find some in your price range made for the type of riding you want. they're all good really. my ride ex bindings have never let me down.
