I remove the engine & gearbox as 1 unit, though it is possible to remove engine and leave the gearbox in. bit tricky as space is tight though!
You can remove the entire front end which makes the job dead easy. take off the bumper, grille and slam panel. then drain the coolant and remove the rad. then get your engine crane hooked up, remove the top nut from the front engine mount. undo all the cables, wires etc till engine is free and lift the engine till it comes off the mount. then remove the front subframe by undoing the 2 outer 17mm bolts, remove rear and box mount bolts and pull the engine out!
For the driveshafts what I do is jack it up 1 side and remove the wheel, then poke a screwdriver into the brake disc vents to stop it spinning. crack loose the driveshaft bolts i can reach, then remove screwdriver and spin it round to get to the next lot, repeat till all out. Oh if the brake disc retaining screw is missing just thread a wheelbolt in to stop disc spinning. another way is to jack it up and get a helper to hold and move the wheel while you crack loose the bolts from underneath.
another tricky bit is the inlet and exhaust manifolds, if you cant get to the bolts split the downpipe from the front silencer and drag it out with both of them attached, as long as its not a 16v this will work. alternatively you can split the manifold from the downpipe, if its a carb this is easy as it just has 2 big clips, if its a gti type the studs may snap. you'll need to do this either way if its a 16v as there is a big resonator box that wont fit thru the gap. I usually remove the manifolds though, your call here.
An alternative option is to leave the shafts on the box, and just drop the entire engine and rear subframe as 1 unit, this requires that you disconnect the UJ from the steering rack which is doable with the engien in just a little fiddly, and undo the top retaining plates from the front shocks. then its just 4 bolts underneath to release the subframe. if you do this though the car obviously needs to be supported on the front, so it depends if this is practical for you or not. Ive seen peeps knock up some big castor wheels on a lump o wood and bolt this to the car using the subframe bolts, so thats an option
