There're a lot of sizing charts available online if you do a little research. That being said, a 152 will most likely be decent for you. Relative to your weight, it's small enough that you won't have to fight too much with it for control. I'm 145 lbs., I learned on a 157 and I had a pretty hard time of it.
Basically the shorter the board is, the easier you'll be able to turn while going downhill (or while doing jumps, once you start progressing.)
It's a pretty ancient board, I couldn't find any reliable reviews of it. From what I could find, it's pegged as a freeride board, so it might be a little on the stiff side flex-wise. It'll most likely be fine for learning on. Good luck this winter!
Thanks for the replies, guys. Another question though. How does the flex of a board affect the quality of the ride on a snowboard? I am big into longboarding, but they dont flex anything like any snowboard that I've ever seen.
