If you have your eye on the attack banana why not?
Should be a pretty good all round board, but if you plan to ride it in Japan I would say you want to go a bit longer than 159 at your weight.
I am 80kg and ride a 157 for most conditions, but when its deeper than 40cm or so (pretty often) I will be on something longer. Since you want a 1 deck quiver I would advise a 161 wide if they have one. Bit more stability and float in the powder. Will still be fine for jumps.
If Japan is where you do most of your riding go longer still (163/4).
Here in Japan you don't know how many Aussies or Kiwis I have seen stuck in waist deep pow with nowhere to go but unstrap and do the stamina sapping hike back to the piste.
As for bindings burton cartels or missions would probably fill your needs nicely without being over the top in terms of price.
Boots, you must try these on and find the best fit for your feet.
