The three must have tools I think you need for bowl turning are one round nose scraper, and two gouges. One gouge with about a 45 degree bevel for the outside of the bowl, and it does well on the walls on the inside. Another gouge with about a 60 degree bevel for going through the transition and across the bottom. For nose profiles, I don't use a swept back gouge much any more, and prefer the standard fingernail grind, but if you do shear scrapes (handle low, and non bevel rubbing cut to clean up tool marks) it does have more cutting surface for that, and if you use gouges for roughing, it has a longer steel edge to take off more wood in one pass if your lathe can handle the torque needed.
The scraper I prefer for heavy roughing. I also use it on edge for shear cuts to clean up tool marks. It comes in handy for sweeping across the bottom of the bowl which is a problem area for a lot of turners, in that is takes a while to figure out how to get the ripples out.
If you go to You Tube and type in robo hippy, I have a couple of clips up there showing gouge and scraper usage.
Of course, the number of toys you have is only limited by your budget. Finding a local club is a huge and cheap learning experience, and you can ask all the questions you want. No embarrassment at all because we have all "been there, done that a couple of times".
