Beginner- what dims should I choose for my height/weight?

I'm a beginner with 1 year experience on a wavestorm. I have a bad arthritic shoulder that i just had surgery on 2 months ago. Supposed to have fixed it completely but still have pain which I'm hoping will still improve as time goes on. It was an ac joint resection via keyhole which I've read can take up to 1 year for scar tissue to fully form.
I'm 230 lbs 5"9 weight lifter.
I want to get a longboard that can do both hp and nose riding. Looking at this board here: http://naturesshapes.com/b_HP2.php
9"2 is the longest I'd venturing in getting because that will just about fit in my suv and in my garage when standing vertically on a stand.
I'm not sure what dims I should get in regards to width and thickness? Should I go big 23 and 1/2 and 3 and a 1/2 or would i regret that? I want to catch as many waves as possible while still being maneuverable.
