RE: right or left
I just started a couple of months ago, but I did like Jack suggested. I'm right handed but left eye dominant and since I figured I was learning from scratch I might as well learn how to shoot left handed. It felt awkward for a couple of days but now I'm glad I stuck with it. My wife thought I was crazy but after watching me shoot right handed and left handed she was as convinced as I am. I could shoot about as good with either hand (which at this point isn't realy very good), but I had to concentrate a lot more right handed to shoot as well as I did with little effort left handed.
