First. let me commend you for going out there and turning - ham handed and all! The best part about turning is there is a starting point and from there it is all in the gaining of experience and how you apply what you learned!
I think I see part of your problem - from your post. You state that the curve was not very graceful. That is indeed something that makes scraping more difficult. When you make your first couple of bowls, it is best to have a good example of a bowl close by to compare what you are making to it. A cereal or soup bowl from the kitchen will work just fine. Notice the gentle curve from lip to base. You can make yours just as graceful!
When turning a bowl, it is a good idea to use your bowl gouge first and have it go from lip to base inside the bowl, Then when scraping, it is best to go from base to lip. If you are scraping to remove tool marks - which is the proper application - it is a good idea to hold the scraper to the wood at an angle - about 40 degrees. This will have the effect of removing the grooves without changing the profile too much. It will also help you to be more graceful in your movements. Finesse is more helpful - especially if you are ham handed. It took me a while to gain the needed coordination, as well!
If you never want to scrape, then that is up to you. But if you plan to never scrape, then you will need to become extremely good with the gouge or with sand paper!
Oh, by the way, how are you sanding? Are you using a power sander or are you doing it by hand? If you were to invest in a power sanding set up($150), you could shave about an hour off your sanding time!
