Hi @rdck
You may have already found this, but here is a great stackoverflow forum that talk about finding more address data from a lat / lng:
http://stackoverflow.com/questions/4013606/google-maps-how-to-get-country-state-province-region-city-given-a-lat-long-va
You could either read in the url via PHP (server side), or do it with jQuery (client side).
Good luck
Cheers
