If not, is there any reason I couldn't add 2 more NICs and at least set the netmasks for the 4 NICs each have a quarter of the class C and connect three to an inside hub? I've never configured a firewall (ipchains) for more than 2 interfaces. Is it doable?

Could you word-wrap please?  It makes your text easier to read.

Really, this is not a good idea, and if the hosts inside aren't reachable
from the outside at all, use the private address ranges (192.168/16,
172.16/12, 10/8).
