One option is the Census TIGER database which is freely downloadable 
(http://www.census.gov/geo/maps-data/data/tiger.html) and contains 
mostly shp and dbf files.  With some massaging you can combine this data 
and put it into a GIS aware database (or just brute force it) to get any 
of the data you need.  Some of the smaller data sets contain just county 
lines and some address data.  The larger files contain every known 
address, county lines, city boundaries, and more.
