IMO, the only difficult part about doing clutch work is putting the transmission back on the car. Working with the pressure plate / clutch / flywheel should be easy.
I don't have a Zspeed unit, so I am not sure how much assembly is required before mounting it on the trans, but perhaps one of the fittings is not properly secured to the unit and it is leaking.
Here is a link on how to bleed the clutch:
REQUEST: DIY Clutch Fluid bleed/swap/replacement.
I was actually able to do it myself, by rotating between the master cylinder, to monitor fluid levels, the clutch pedal, to pump it several times, and the bleed valve to release the air, it probably took 30 minutes, not including the time to put the car on jack stands.
