Yes label and take pictures. I've done this job quite a few times and still always refer back to the photographs I took. Harnesses do pretty much fall in place but figuring out routing wires and vacuum lines can drive you nuts and waste time.
Get a piece of cardboard and put your upper manifold bolts in it in the same position that they came out. While they all will fit some are different lengths. I have seen a long one put in the spot under the fuel line and begin to wear a hole. Not good.
I pull the engine with the manifolds on. Some prefer to take them off in the car.
A/C compressor- Unless you are going to replace it I just unbolt it and pull it up and over and tiewire it to the passenger hood hinge.
Remove the hood.
