>IPCop can require RADIUS authentication on top of the MAC filter.

Fine. Enable it then. I assume it uses 802.1x for wired too.

>I just need to find the easiest way possible for my users to deal with the RADIUS piece of the model.

Simplest thing for your users with Win XP/Vista would be PEAP. Setup is
the same for wired and wireless. Connection/Properties/click on
Authentication tab/tick enable 802.1x box/select PEAP from the box/click
on Properties button/
