I've done it both ways and it all depends on how much space, how many bodies are available, and how big a hoist you have.  Single-handed in a single-width garage and with a folding hoist I've done engines three times including a V8, and even when the V8 gearbox needed to come out I did the engine first and got the gearbox out afterwards which makes dealing with the gearbox crossmember easier.

But if all you need is access to the engine or clutch then engine only is far easier as dealing with the gearbox crossmember and the speedo cable (when on an OD) is the big problem getting it out with the engine, and everything else you list is extra work that isn't needed.  Getting the two back together is the same whether they are both out or the gearbox is out as well - with one exception I'll come on to.  With the gearbox out both need to be held to get them back together or they wriggle about like small children in the bath, doing that on two occasions with two people it took longer than getting engines back in on their own.  With the gearbox wedged at the top of the tunnel that is held still while you are manipulating the engine and only needs one person.  

The exception is that on chrome bumper models you can't lower the engine in then push it straight back onto the gearbox as the crossmember is in the way, it has to be done at a steeper angle until the end of the first motion shaft is inside the clutch cover, then reduce the angle and it will go back.  With rubber bumper models as in your case with the body sitting higher on the crossmember the engine can be lowered in and pushed straight back.  Believe me, it is far easier doing engine only, and that is how the pros do it.

  The workshop manual recommends removing the engine and gearbox as one unit.  Has anyone had success removing the engine while leaving the gearbox in place?  All bell housing bolts appear accessible, and a friend would love to not have to remove the console, carpet, gearshift, driveshaft, etc., to get the engine out--the head has serious problems, and he fears the block will too.
