I do all my iptables configuring from the command line. iptables config is
store in /etc/sysconfig/iptables. This Tutorial for iptables should be able
to help you.

Port forwarding is really not that hard. The big question is if the
forwarding to another port is on the same box or will you be forwarding it
onto another box? If it is staying local then you want to look at REDIRECT
not forwarding. I.e.,
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 8080
If you are truly going to forward it onto another box then you need to look at
DNAT.
