My solution is to a somewhat larger problem--the user chooses from a wide variety of place names using a hierarchical browse that is brought into view using a sliding jQuery panel. This is at http://mrdata.usgs.gov/general/map.html and is invoked by clicking the green box labeled "PLACE NAMES"
The data infrastructure behind that is composed of a PostgreSQL table containing the area centroids, a formal thesaurus containing the place names themselves, the latter accessed using a simple web service written in PHP. You might be able to do this using a static JSON file, though, if you have far fewer places. The Javascript code at http://mrdata.usgs.gov/general/map.js shows how I call the OpenLayers function to zoom to the appropriate position. The actual zoom level for each area has been stored in the database along with the centroids. So this problem is a mixture of data and code. You probably can rearrange the code and data in many different ways, different than I did.
