Keep It Simple, Eh?!
You've got a bowl gouge that will work fine for normally shaped bowls in the size you are planning to turn. An Ellsworth grind will allow you to work from top to bottom inside the bowls and out.
Now go make 100 of them. When you've done that, you can make things as complicated as you like, with confidence.
Norm, Dean is giving some good advice here.
Don't get too wild with buying tools just yet......but, you might want to consider getting another gouge the next size smaller for starters. Once you have some time in the saddle, you will have a better idea of what you want......so, go make some bowls with what you have. Remember that all tools have one thing in common.....a sharp edge. If you can present that sharp edge to it's best advantage, you're going to get a good cut.
Right now, you're probably going to try a few different grinds, and developing proficiency in producing those grinds......so, you're likely to use up some steel fairly fast in the beginning. That will slow down some, once you know what you want with the grinds you've chosen. Sorby is good.....not the most expensive, nor the cheapest......good for starting out.
Your Sorby is probably M2 steel, and it's an excellent steel for woodturning. I'd stay with that for now. Many turners decide to move on to harder exotic steels as their proficiency gets better. Nothing wrong with that, and the advertising says the edge will last longer. Who could argue with wanting your cutting edge to last longer, right? It's true, the edge does last longer, but the sharpness zone between just sharp enough, and not sharp enough, is problematic from my POV. I've explained this more detail elsewhere.
Anyway, I have some tools with harder steels, but my mainstay is M2 for all my turning.
Your skews have very limited use for bowl turning.....and even at that, they are used in ways they were never intended. Skews are for spindle turning. I don't use them at all for my bowls.
There are some great books and commercial dvd videos on bowl turning. There are some good free videos on YouTube, but for the beginner, I'd suggest you get some of the commercial videos.......until, you have some basic concepts of safety, and what you personally want to do on your lathe.
Sorry for being so long-winded!
