Well I've got all of the easy part done. Actually the P/O tried to rebuild and the leak appears to be from the e brake actuator. How do I get this thing apart? the only thing left to do is remove the plug, but I didn't want to do it unless I have to.
The piston in this side is stuck in, I tried to pry lightly, but didn't want to put too much pressure on it incase there's something I might break.
If anyone has any reference material the Haynes manual glosses right over this.
Any help would be apreciated

Check or search Eric Shea's posts.....he did a blow by blow essay on rebuilding the rears. Haynes and Porsche will tell you it can't be done.
The leak is NOT from the E-brake, There is an O-ring on the adjuster screw that keeps fliud from escaping in that direction. You must remove the adjustment screw. It is held in place by a cir-clip at the bottom of the piston bore. You have to split the calipers to get to it.

So, there is nothing that holds the piston in on the side that has the e-brake actuator? right?
This is where you should look;

Not sure how to say this. The fluid/hydrolic movement of the piston is isolated from the Ebrake mechincal actuation. There is no fluid where the Ebrake actuator enters the caliper body. The 5mm hex adjuster rotates a shaft that sets the pistion position. There is an o-ring on the shaft where it enters the pistion bore. The o-ring keeps the fluid from leaking out. The Ebrake actuator pushes on the outside end of this shaft, which slides in/out a bit, in turn it pushes the piston against rotor. It also displaces some oil causing the inside piston to clamp as well.
Ok - or is this even more confusing??

BTW...
Posts 6 & 7 (in the link Lou posted) show the clip and the o-ring on the adjuster (respectively).
Here's a (bad) picture of the gear you're probably missing...
