Your proposed configuration is pretty close to what I've been running for
several years (my original server had an AMD K-6 and ran Red Hat 6). The
hardware is way more than sufficient. I have CentOS doing the natting instead
of the modem. Just use the modem as a pass through.
Pretty much everything I've done is documented on my blog at
http://davenjudy.org/davesBlog. I describe what I've done on the blog and that
way I document what I did for my future use and someone else might be able to
use it.

Don't do clamav since I even got my wife to use Linux. No real need for squid.

See my blog.

I just used public keys for ssh and disabled password login. I also suggest you
move the sshd port to something non-standard just to cut down on the fruitless
attempts to login there. The script kiddies generally don't scan to see if sshd
is listening on a non-standard port.

3rd NIC is probably the easiest with a crossover cable to the WiFi AP. That way
you can easily set up specific firewall rules for the WiFi traffic.

Hopefully, someone else can help you with these.
Most of my recent blog posts deal with setting up IPv6. You'll need to look
through the "CentOS server set up and maintenance notes" section for some of the
older articles (DHCP, RADIUS, etc.).
