I'd recommend using the TIGER/Line data from the Bureau of the Census.
The applicable GRASS commands include v.in.tig.basic, v.in.tig.lndmk, and
m.in.stf1.tape (which is used to extract just those records that you
desire). I believe that there is a short tutorial for these commands on
the GRASS ftp site.
