Here are a few ideas that come to mind.

a) Don't allow ANY connections to the firewall from the net. Administer the
firewall from its console or from systems behind it. Restrict which systems can
connect to it.

b) Allow only the outbound traffic from the server that is essential to its
operation.

c) Use a minimum of rules (for speed).

d) Configure the firewall with FASTACCEPT=Yes (again, for speed).

e) Configure Shorewall to start before the network interfaces are brought up.
That means that you cannot use any Shorewall feature that requires interfaces to
be UP when Shorewall starts. This avoids momentary "holes" during boot up of the
firewall.

If the firewall is administered properly, there should be no additional security
offered by NAT. On the other hand, NAT offers protection in the event that the
firewall is accidentally opened. I don't believe that the effect on speed is
significant but then I haven't measured it either. So long as you have fast
enough Firewall hardware, it shouldn't matter anyway.

Hopefully other list readers have additional suggestions for you.
