Stew,
First, welcome to the forum.
Now to answer your question, there are a few basics but everyone has their variations. I have a much longer bevel on my skews than most people, some have 3 or more bowl gouges with different angled grinds for the different parts of the bowls. So basically, the grind is what you create and what you get used to.
But there are some fundamentals and if you search the interweb, you will find lots of examples or descriptions, having said that, for bowl gouges, one of the most useful grinds is the Celtic, Long, Sweptback or Ellsworth Grind. That,s 7 inches back from the centre of the wheel, 4 inches below the center-line of the wheel and 2 inches protuberance of the tool, see the pdf I've attached.
Yes it shows a grinding jig in use, but these are relatively easy to make from scraps and bits and pieces you should have hanging around from your Knife making work.
