ok, I'd take the advice of Autopilot, much easier, and you don't have to worry about the other computer slowing you down, having problems, etc...
For your purposes I would think a 4-port wired one would work? Of course it depends on where each pc will be located.
The following is a link to a recertified D-link 604 router. Fairly decent price, and easy install setup...

NetworkingIf you are going to be adding a laptop in the future I would recommend a wireless network with a router that you can run physical wires to as well as wireless conenctions. My dad just got the US robotics 8054 for christmas from his friends at work and it has 4 wired connections and wireless capabilities of over 300FT...
Whatever you look into I would highly recommend looking at open-box, or recertified components making sure that you still have a return policy.
I myself have used the following:
DI-604 (Wired) From tiger direct. easy setup/install and easy to configure for fs, etc...
and of course just yesterday started using the US Robotics 8054 wireless router which seems to be pretty nice so far..:-)
Do what you want to do, but this would be a good practical way instead of going through another system first...
As for internet access on more than one pc as described above with a router you shouldn't have any problems with your ISP. Each pc will have a IP address in communicating with the router, the router in turn will have ONE IP address in communicating with your ISP service.
At least this is how it works with SBC Yahoo DSL...
PM me if you have any questions regarding this info..;-)
