NAT+SPI vs Software Firewall

I have a Netgear DG834G v4 that has inbound services set on BLOCK Any(All) with outbound services set to Always (allow) by default.

If I was to block all outbound services and leave ports:
5060 open for VOIP,
80 for HTTP,
53 for DNS,
143 for MSN.
With a good anti virus would this be more effective than lets say zonealarm security suite running?
OR is it recommended to have two firewalls running?

On a side note some people say it is unnecessary to block your outbound unless working in a corporate environment. What do you think?

Moe.

Agree with what you saying but is it a better way to rely on the inbuilt firewall in the router if setup correctly?
I would imagine it would be quicker because it is at a harware level. Free up some resources by having the software firewall switched off.
