Thanks John, with the hood, hatch and bumpers, masking tape and cardboard are your best tools to prevent scratches. With the front fenders removed I cover the cowl area and sides of the engine bay with cardboard and tape it down. Then with the front edge of hood resting on my waist and holding the sides I walk it forward and lay the hood in place.
Then I lift the front edge of the hood and put something on top of the engine, a small cardboard box works well, you just want to give yourself enough clearance to install the hood hinges and springs as one unit so the hinges are in the open position. Now tape the top on the hinges for safety and pull the hood forward and install one bolt on each side of the hood to the top most hole of the hinges, once that is done you lift the hood up pivoting on those bolts and install the other two bolts and you're done. Remove all the tape and cardboard and start preliminary alignment.
The bumpers are very similar, tape up the sides the fenders and quarter panels, make sure the bumper mounts are already installed on the car, get all your fasteners and wrenches laid out on the floor so they are easy to grab and ease the bumper into place, secure one nut in the centre section then move over to the far side of the bumper and secure it, once those two fasteners are on the bumper will sit there nicely so you can get to the rest of the fasteners.
Expect to install and remove the bumpers several times as you add washers to get the depth and alignment right.
I like to tape the weatherstrip in place on the car for at least 24hrs so it relaxes a bit and I don't have to fight the twists they acquire while folded up in the packing bags.
It seems like the J hook for the battery hold down and rear P/S splash panel always go missing on these cars, I've got pretty quick at making up replacements I've had to do it so many times.
