Even more important than stats is what kind of riding you are into. Do you like jumps, rails, pipe, all of them or do you just like cruising down the hill?
Do not go for a combo set unless you are allowed to choose the pieces. You don't want bad product forced upon you because the board, boots, and bindings are all the same colorway. You want each piece to tailor specifically to your needs as a rider.
Also, are you going for a whole new setup? If so than the first thing you need to do is go to your local shop, tell the rep how you ride and start TRYING ON boots.
Boots are the most important piece of equipment you buy as they initiate anything you want to do on a snowboard. It's risky business just ordering a boot online. Each boot fits differently, flexes differently and laces differently and you need to be able to feel that difference before you make a decision.
Let me know your riding style and we can talk boards and bindings.
