Converting Campag wheel to Shimano. What do I need?

on-yer-bike

Im thinking of changing my Neutron wheels to accept 9 speed Shimano cassette. Is this the only way:

Neutrons however arent in the list of wheels that this freehub will fit for some reason.

or can I buy sprockets that will work with Shimano but fit on a Campag free hub?
