I run some what of what you want to do.
I have 2 nics and I went in to the setup on my system in mandriva I go 
to my GUI tools they call setting up the computer, anyway I go in and 
setup the 2 nics as 1 is my dsl connection and 1 links to my laptop.
On my desktop system I run shorewall firewall and also have iptables 
installed and in the shorewall configuration is where it lets me set it 
up for my loc (local network) and net (internet ) to allow it to feed 
through from eth1 to eth0.
eth1 is my loc and eth0 is my net. there are many ways to open spacific 
ports with it for other apps, but you can read up on shorewall on how 
your needs are.

If you have a GUI interface that lets you configurate your computer for 
networking, then thats your best bet and there if you have it to config 
sharing the internet connection. Like I said, I run mandriva and that is 
what I run and I just thought I'd mention what I did just in case you 
have similar tools on yours.
But if you do use shorewall, read up on it as much as you can to 
understand all you can and can't do...
