1 Hub, 3 computers and 1 IP address, how do I connect all for the internet?a

I am running Win K on two of the fastest computers and Win 98 on the third.  I my primary computer I have two NIC cards and a single in the other two.  My ISP will not allow 2 IP addresses per customer.  Therefore I have to do an IPconfig/release and IPconfig/renew, each time I wish to change a particular computer to an net connection; a hassle to say the least.  All 3 computers NIC cards are connected through a NETGEAR hub.  I also would like to be able to file and printer sharing between the three systems, but with this IP addressing issue this has caused allot of problems.  Surely there is reasonably simple a solution for this problem.  I would be very grateful for any help with this predicament.
Thanks ahead of time to all.

Discard the Netgear hub, and buy a Netgear Cable/DSL router -- it's under $100 US.

Connect each of the PCs to the router.
The router will take your one IP-address provided by your ISP.
The router's DHCP-server will provide "private" IP-addresses
to each of your PCs (if you enable "obtain an IP-address
automatically" on each computer).

The router will also act as a "personal firewall"
to keep hackers ("Code Red", "SubSeven", et cetera)
out of your computers.
               
The router will also enable computer-to-computer communications within your private network,
e.g., file-and-print-sharing.
"In my primary computer I have two NIC cards"
Do example 1 that jimwasson proposed for no cost.

One NIC card to the hub and connected to the other machines, and the other with a fixed IP to your ISP.
Enable IP-routing on the primary computer and install some sort of firewallsoftware.
 
You can hide your network behind an Internet Gateway Router with Network Addressing Translation enabled and setting it up as a DHCP server you won't have to worry about subnetting your network besides it is a good firewall you will also share your internet connection between all the computers in your LAN
I personally recommend the Netgear RT311 for about $80.00 is a good investment and protection from the hackers.
What I have done in the past is installed one NIC card, and two instances of TCP/IP (This was done on Windows 98 SE) and subnetted a different set of IP addresses for my LAN.  This worked well, but I haven't been able to do this on Win 2k.  You might find a way to do that, then you could set up a proxy on that machine and not have two nic cards installed.
