I ended up with the following on my samba PDC:
-A RH-Firewall-1-INPUT -p udp -m udp --dport 137:138 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp -m udp --sport 137:138 -j ACCEPT
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 139 -j ACCEPT

Note that 137 and 138 use UDP rather than TCP.

The following were neccessary for making samba a WINS server:
-A RH-Firewall-1-INPUT -p udp -m udp --dport 1512 -j ACCEPT
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 1512 -j ACCEPT
(Well, I probably only need one of the tcp/udp, but opening both 
shouldn't cause any security meltdowns at this stage... and it was 
easier than figuring out which are actually neccessary.)

445 doesn't seem to have been neccessary for my purposes, YMMV.
