UNfortunately I don't use GUI firewall tools, I am a crusty old unix
admin...

I am also not particularly skilled with iptables, having not had to
mess with it for years.  (at work we have proper firewalls and at home
my ADSL whatsit does the job)

The stuff below looks reasonable from what I can tell, 

however...  the none out might be a problem.  Because well.. stuff has
to go out :)

I'd have thought you meant to put none in, all out?

You don't care what leaves the premises but you are very much
interested in what comes in.  Ideally you don't want anything coming
in you didn't ask for except those file transfers.
