I have a 3Com 3CRWDR100A-72 broadband firewall router. I also run an
Outpost software firewall. I find that Outpost causes problems and is
difficult to keep properly tuned, also needs its annual licence fee to be
paid.
If my PC is sitting behind the 3Com firewall with NAT enabled then do I
really need a software firewall as well? I keep up to date with Windows
updates.
Any thoughts?

Your "firewall router" (I love that term) will permit your PC to connect to
anything, going out. So, any malware you do get has full rein to do
anything it wants to your system, by connecting out to remote hosts.
A personal firewamm *might* help with this, *if* it's properly configured
and doesn't get compromised.

This question is often asked, and it's always difficult to answer because
it's a bit like saying if you have a lock on your front door then do you
need locks on your windows too?
The answer is that it depends on what type of Windows you have, what area
you live in, whether you know how to close the windows, whether you
understand who or what is likely to get through the windows and how they
might get through and under what circumstances, etc.
So the only person who can assess your situation and tell you want you need
is yourself.
The best way to become able to make an assessment of what you need is to
learn as much as you can about the technology behind what you are doing.
Your message gives me the impression that you are knowledgeable enough to
understand why additional firewall software is not likely to be worth a
license fee.

If that router can stop inbound and outbound traffic by port, protocol
IP, and has logging, then you can dump the PFW solution. If the router
cannnot stop outbound, then you'll want a packet filter or PFW that can
stop outbound traffic from the computer as some people supplement the NAT
router that cannot stop outbound. It's as simple as that.
