What I have been doing so far is going through /etc/rc.d/rc.local and
commenting out the old ipchains lines, adding in the same thing with
iptables instead. Is this correct?

    # 1) Flush the rule tables
#    /sbin/ipchains -F input
#    /sbin/ipchains -F forward
#    /sbin/ipchains -F output

     /sbin/iptables -F INPUT
     /sbin/iptables -F FORWARD
     /sbin/iptables -F OUTPUT

# /sbin/lsmod
Module                  Size  Used by
nls_iso8859-1           2832   1  (autoclean)
iptable_filter          2256   0  (autoclean) (unused)
ip_tables              11936   1  [iptable_filter]

Looks like ip_tables is being loaded...
after replacing the ipchains lines above with iptables lines, I assume I
just restart networking and I should be good to go ... ?

Anything wrong here?
