Dan congrats on becoming Primal. I personally needed to experience it in order to be fully understand it, glad it's working for you as well.
My two cents:
1- No idea really
2- I'd say stop counting, relax and listen to your body. Cutting sugar seems to bring appetite levels back to normal, so following your cravings should be safe.
3- I have seen everything you mention in normal supermarkets, but not in Whole Foods or Farmer Markets. In my experience, you can request specific cuts to your butcher or in the farmer markets though.
4- Game meat and grass fed cattle can be rich in fat as well. Check jonw's post here:
