I just did the clutch on my Cayman. Should be the same job. I used the Pelican Parts tech article as a guideline.
The engine needs to be supported once the transmission comes off. It will droop to the right side (US passenger) if not.
Brave people do it on floor jacks. I had access to a rental lift and it made life easy.
The tricky part for me: trying to remove the clutch slave. In the end, I just disconnected the brake fluid line and bled it on reinstall. I think that's quicker than trying to remove a bunch of odd things to in tight spaces to remove it out of the bellhousing.
You'll need quite an assortment of tools - torx, hex, triple square - 13/15/16 mm sockets/wrenches.
Ask me if you have any questions - it wasn't too bad - but I've done plenty of (Japanese) clutches and had the rental lift.
