Must be nice to be so sure of your ground :-)
Personally, since I only need ssh access from a few IPs, I prefer not to
have my ssh port flapping in the breeze. I therefore use firestarter to
leave it open only for the trusted IPs.

If I was running ftp as a server, I would probably want to do the same for
that as well (I don't run ftp).

Blanket statements of this kind make me scratch my head. 

Another useful
iptables feature is NAT, which is also trivial to set up with firestarter.
