Thanks.  I did get an answer from the Netfilter IRC that worked:
OUTPUT -p tcp -m tcp --dport 8080 -j REDIRECT --to-ports 3128

Basically I needed the output chain, not preroute.  This works locally
which solves my problem.  I'm not sure if it would work on a
firewall/proxy/router with a downstream PC.
