This statement is confusing. Do you have a base station AND a G3, a third
party PCI wireless card? A Base Station literally on TOP of your G3
(snicker)? Please specify.

Can you ping it from the desktop?

You don't need to switch to DHCP to save address. What you would need to
do is setup NAT (Network Address Translation) by where you have the
AirPort base station, or the ISDN router, or a software package on one of
the machines (IPNetRouter, a Vicomsoft product, or Apple's promised
Airport Software Base Station) bridge to TCP/IP networks and translate.
Whichever you use to do this I will now refer to as "The Router". The
Router will use one of your ISP-assigned addresses. It will also maintain
a second IP address. Typical this will be a "private" address (anything
that begins with 192.168.x.x). Your other machines will be on the private
network, and must have their router/gateway configured as the IP address
of The Router. The Router will then translate any requests they make, get
and fetch the stuff on the internet and then serve it back. As far as the
internet is concerned, every request is coming from the IP address of the
router.
That's probably a not-so-coherent explanation (I'd love to hear Tim's!),
but my main point is DHCP is NOT a requirement for this configuration,
and I would recommend against it with so few machines. DHCP was made to
ease configuration in large networks. This is not your case. Stick with
static-IPs for your interal machines as it is a bit more reliable and one
less thing to troubleshoot in a problematic situation.
