Another thing to keep in mind, in a system like this, is that Texarkana (for example) is one city in two states. They have a street called, appropriately, "State Line".
I get a flat-file of city, state, county, Zip, information from http://www.zip-codes.com. It's cheap and does for what I need. You might want to denormalize that way.
