FYI its the Never Summer SL not LS. The regular SL is last years model it doesn't have reverse camber, this years does. Hunt around you can find tons of reviews and talk about what that is. 155 is a great size for your weight you could even go with a 158 if you wanted to.
Bindings its going to come down to what you want performance wise and what boot you're using. Boots its going to be what fits your foot.
