Sorry, but if you follow Microsoft's instructions, it will leave you open for open ports on your firewall. I have hooked up hundreds of systems, and never had a issue with leaving it as is, and they work.
All you have to do is disregard the whole NAT "Moderate" issue, and you will be fine. The games will work just fine with leaving them as is.
If Microsoft believed opening ports for the Xbox were a security issue, they wouldn't tell you to do it. Here's a post from a guy on the Xbox forums that explains why you should open up just the ports Microsoft identifies (and forward to the Xbox only), and why it's not a security risk. He also explains why you may sometimes be able to play with others on Xbox Live even if your NAT is set to strict or moderate.
