I think you need a wide version for your foot size, but it might depend a bit on your stance. There's a good article on this that hopefully someone else will post on how to measure to determine this. Or if you can go the shop and mount the bindings and boots you can check.
As far as camber vs not camber some people have predefined views on this, in which case I'd say pick what you prefer (this doesn't seem to be the case).
If you ride someplace that's often icy I'd lean towards camber for better edge hold.
You say you want 'to have fun with the board' - this sounds to me like you'd enjoy the looser, skatey feel of the flying V, especially if you tend to have softer snow as opposed to hardpack icy groomers.
Burotn Demo days are your friend if you can get to one.
