Proxies

Help needed, please. We use all cisco networking gear. Currently using a cisco cache engine with SmartFilter to "manage" the surfing for our staff/students. As usual, the little devils figured a way to get around it. They went to Google, entered "open proxy list" and bingo-bango. From this list they found open proxies to use in IE. Besides suspending them, we made one technological change. Outgoing ports 8000, 8080, 8888 and 3128 are now blocked at the firewall. Can anyone suggest further refinements to reduce this kind of abuse? I know some proxies run on port 80, but I'll have to live with that.
