Dan, it is quite possible to just pull the ZF, leaving the engine and its accessories in place. The only tricky part, if you have a later model car like yours is getting the rear ZF mounts out of the way. I recommend removing the nuts on the 3 studs (each side) holding the rear mounts to the ZF cases and double-nut them so as to remove the 6 studs.
Then replace the 3 studs with hex bolts. Otherwise, you will need a long pry bar or maybe a 6' long 2x4 to pry the cases sideways without damage so the aluminum mount castings can be pulled away from the OEM studs, one side at a time. With hex bolts, the next time will be even easier.
Some of my single DIY friends with no engine crane do not actually 'pull' the ZF. Instead they simply unbolt everything and slide it back about 8" from the bell housing. Thats enough space to R & R a clutch. The ZF without a bell housing weighs about 155 lbs so you'll need yourself, two husky friends and some good straps or ropes to lift the bulky oily lump high over the rear body.
While you're in there, its considered wise to also replace the pilot bushing and the throwout bearing, because they are wear-out items and its a lot of trouble to replace them singly.
