does not seem to complicated (in theory), you need to physically seperate
the two networks and put a firewall between them.

how easy the physical seperation is depends on your office layout.

in general:

internet---firewall(cisco)---wifi router+switch---lab computers
                |
     wifi router+switch
                |
         staff computers

i have a similar (more complex) setup using linux and iptables
