@Jennifer - If you have both at this point, I would frankly keep both! I would make sure that another profile is also an admin of the page, just in case FB does something with the profile. But that profile can be very effective at active engagement (i.e., inviting to events, asking questions, tagging photos, etc) and should be considered very valuable.
You can also use this to actively direct residents to your fan page. In other words, you friend them through the profile, and then suggest the page to them. I realize this is not kosher by FB standards, so take my advice with a grain of salt, but this does work. To make this work, make a new friend list within the profile. When someone friends you, or you friend them, add them to this list. That way, you can track who you have suggested the fan page to and who you have not. You simply clear out that list whenever you invite them to the fan page every so often.
