i want to start a facebook for my product/store. do i sign up as if i were making one for a person?

Sign up as a person initially. Then you'll want to make a group. Here is where you can advertise your product/store. You're going to need to "invite" people to join your group though, so perhaps placing that link on your myspace page or any other pages you may have will create more traffic and views for you. Then people searching facebook for your product/store will fall upon the group you created.
