Chuck maybe others will disagree with me but on a bowl I would use a bowl gouge. A spindle roughing gouge or a simple spindle gouge IMHO is just not the right tool for bowl turning. I agree with Vaughn that a sharp bowl gouge is also my choice and have used a scraper on the inside cutting at a 45* angle. I don't use a skew much on bowls but as Stu said it needs to be scary sharp as in shave your arm sharp.
Two DVD's that I would recommend are Bill Grumbine's Turned Bowls Made Easy and Mike Mahoney's From The Tree To The Table. Both are excellent. Both show you different ways to deal with endgrain, different cuts for different situations, sanding, etc.
