What the shop guy is probably saying is you will need to consider de-tuning your nose and tail of the snowboard. This helps to prevent edge catching at this point. Also if you are a fairly new rider riding greens and maybe blues you might want to consider beveling the side edges on your snowboard. See the above article for further information, or the below excerpt from Copper's website.

"Burton has built boards, boots, and strap bindings specifically for the learner. The LTR Board has an Ultra-soft torsional flex profile to help you initiate turns. It's got deep sidecut to pull you into a natural carve, long transition zones for easy turns, and a 3-degree edge bevel to prevent hard falls. "

I imagine I will just probably take it to a shop and have them explain and hook it up.
