The configuration you mention here would work fine. It's recommended that
you enable WEP security on both units to ensure no one can easily sniff
your network.

The D-Link equipment while reasonable, is not the best when it comes range
and link quality.

It is possible to setup a point to point link between two computers to
allow the second to access the wired network that the other is connected
to, but the computer which has both a wired and wireless connection need
an operating system that support routing or forwarding of packets.

If the machine is being used as an Internet gateway already (such as
connection sharing of a modem link), the software would easily allow
sharing of the Internet connection, but may not allow access from the
wireless network to the wired network. It all depends on the OS and it's
configuration.

If you're looking for cheap cards, some members of the Sydney Wireless
group in Sydney have Enterasys/Cabletron cards which support 40 bit WEP
for sale for $50 each. Check out http://www.sydneywireless.com/ for info.
