Drupal is HOT in NYC

I'm working on a site that is a database of apartments in NYC. I would like to relabel or use more/different fields in the Location section to make the submission form more compatible with NYC addresses. Particularly I would like to have a field for "Borough," "Apartment #," and "Neighborhood." If I could change the label "Additional" to "Apartment #" it would solve that field, and I could even go with changing the "City" label to "Borough" but would prefer a drop down list rather than a text field input.
