A 10/100/1000 would always be better for adding other devices, than a
pure 1000 switch - such as additional PCs that are being used on a
temporary basis, routers, etc.

Don't you also have a video and power cable to your workstation?  What
difference will the addition of a network cable make?

Don't forget that WiFi is a shared bandwidth solution - like the old
network hubs were.  This is the reason for the pathetic performance per
PC.  Remember, this is why we've all moved to switches - way faster

Also, MAKE SURE that all machines on the WiFi network are running the
same protocol - all 802.11b or 802.11g, but not a mixture of both.  If
you have a mixture, use one 802.11b AP and another 802.11g AP as this
will increase net throughput.

Definitely.  You can then assign a different network to the WiFi PCs and
filter the traffic through the m0n0wall.  Also, make sure that you
implement WPA security - WEP is a joke, MAC filtering isn't much better,
and SSID hiding is not even worth the waste of time to set it up.

I've seen reports that Intel Gigabit Copper NICs work fine.  I'd also have 
expected this as they have a single driver that supports almost all of their
