I recommend installing as a unit since it is a lot easier to align a bell housing and install the clutch and trans on the floor than from under the car.

As a side note, if you ever want to remove the trans separately and need to remove the tunnel, I've found that a nice sharp putty knife with a liberal coating of WD40 will cut through the black goo. Just keep applying the WD40 so the black goo doesn't stick to your knife.
