Donna,
In answer to your question, a fan page is generally what is used if you already have a personal facebook page. I use the fan page. If you don't have a personal facebook page, you can set up a business profile, which is what the celebrities use. This separates business from personal. As you are only allowed one profile, you can't have a personal and a business profile, hence the fan page. One thing, if you have a personal and a fan page, be prepared for some to request your personal page. I'm not sure why, but they do. If you accept them, you can put them in a friend catagory, which is what I have done.
