Really good setup for a beginner.
You may want to look at other boards but the Ripcord looks fine. It will be nice and easy to ride, but since you seem to be pretty good a board sports you might out-skill pretty quick.
What kind of riding do you eventually want to do?
I'd go with a 152-154, wont be too big and you'll grow into a bit more.
With 10.5 sneakers you'll probably be closer to a 10.5 boot. MAKE SURE to get a boot that fits and is comfortable. You should be ok with a 10.5 on a regular width board.
