Here is a link to an extremely comprehensive tutorial on Facebook Pages, on Squidoo.
Mark's (Pixelrage) Squidoo lens covers topics from "What is a Facebook Page?", "How to create a Facebook Page?", to promotion, statistics, customization. All illustrated with nice, easy to follow screen shots.
Definitely worth checking it out. You'll leave the page armed with a little more knowledge even if you have a Facebook fan page that you are successfully running.
"Facebook Pages are important for a few reasons. They've been showing up high in search engine positions. Also, you can get unlimited "fans" for your Facebook Page, unlike the limit of 5,000 friends that your regular Facebook Profile is capped at. They're visible to search engines and visitors, too. It's almost like a social networking mailing list that you can reach out to at any time!" ~Pixelrage, "How to Create a Facebook Page"| Squidoo
