Firewall questions

Hi All, I am using SuSE 7.1. Having finally gotten online, I need to learn about using SuSE firewalls. This is new to me so I have the following questions. First, should I use the firewall that came in the distro or is the firewall2 Alpha on Marcs page better? Should I then use SuSE harden as well? Finally, I would like to learn more about firewalls so that I don't have to ask questions like this one :o). So what would be some good books to read on the subject?
