I'll echo Wire's sentiment. In any home/small office situation I've been in a router has been in place.
All of the modern ones I've dealt with have some sort of firewall capability. Though most of the need for one is taken care of with nat-ing.
I'm not familiar with what Zone Alarm Pro does. Do you want to do more than just block unsolicited traffic to your devices?
