With the machines you have, I would suggest a setup somewhere along the
following:

 56k modem/DSL/Cable
      \
        \
         486[1] --- hub/switch ---- P90
                     /     \
                   /         \
                P2/400       P3/500

(And remove whichever one later you want to remove.)

[1] The 486 you set up as GW box (if you want, you can run NAT/IP
    Masquerading on it).

If you choose to go the NAT/IP Masquerading route, I'd suggest reading the
IP Masquerading-HOWTO (or mini-howto) - it has a nice short step-by-step
process for doing this. As for how feasible this is to do - we do NAT at
work (we have approx. 2500 machines on our LAN/WAN, all firewalled/NAT'ed
through one poor Ultra10...

If you choose to give all 3 (4?) public IP's, then all you would have to
do is set the routes on the 486 to point to the correct interface for the
various IP/s.

Small plug here - I know the gear is expensive, but I am biased towards
Bay Networks (maybe soon to be called Nortel) (mainly because we use it
exclusively and have had very little problems with it.)
