spf and masquerading


Just two thoughts: 
a) Statefull packet filtering would be quite senseless
   if I applied it to a masquerading server because that would not allow
   connections to hosts other than the firewall (exept I explicit programm
   them). Right or wrong?
b) On a normal host, spf is only good to avoid opening all ports above
   1023, right? But in case I deny connections (SYN-Flag) to those ports,
   will it bring me any advantage?
