I setup something similar that may be useful....  We have a small office 
with a 12/24ths of a T-1 line for an absurd amount of money as our primary 
connection.  Cheap residential cable service became available with 
quadruple the bandwidth [incoming only] for cheap.

I installed an extra NIC the to cable modem and setup the Squid proxy / 
cache on a f'bsd box that was already running other services.  Then used 
some Squid options and IPFW to get all Squid's traffic running over the 
cable line.  This gets us faster web and ftp downloads, and off-loads the 
T-1 for other things.
