Internet sharig and file sharing are two completely separate issues.

1) I am on a hub and I have two separate cards (one for the Internet and 
one for home/office): setting is much easier and safer, and traffic is 
completely separate.Adding a card is cheap and easy.
You set the first card to Internet and try it: if it works you set the 
network parameters on second card.
But you have to tell the machine that is a router (see file /etc/systcl.con)

kernel.sysrq=0
net.ipv4.ip_forward=1
net.ipv4.conf.default.rp_filter=1
kernel.core_uses_pid=1

At this point you must tell the machine that must do some NAT (Network 
address translation) by setting appropriate iptables file in /etc/sysconfig
This is mine...with eth0 card to the internal and ppp0 as Internet 
connection

Samba configuration in a separate message after confirmation of success!!!

In any case I suggest to Install Webmin (that you can download at Www.webmin.com)
