I'm close to your size and I ride a 146. I'm a little shorter (5'3) and weight 112. I also wear a size 7 shoe. I used to ride a 143 and switched to a 146 this year. I didn't notice that big of a difference between the two, but my previous board was a plank so anything felt better than that.
As you said the technology isn't important to you, the camber should be perfect. I prefer a rocker/camber hybrid, but if I only had to chose between rocker or camber-I'd choose camber. The rocker feel might throw you off if you're just learning as since it has a much looser feel. Also the rocker is better for freestyle while the traditional camber will be best for all mountain.
Hope this helps!
