Generally, pieces of foam pipe insulation available at a hardware store make great protectors for tubes. They're split down the middle and wrap around. They do have adhesive strips, but don't use those (use zip ties or tape) because if you do, you can't re-use them!
I make sure there are no loose parts in the box -- nothing that can come loose and scratch or bang anything. A spacer in the fork can be picked up at any bike shop - they just throw them away. And, once you take off the bars, you might want to secure them so they don't rub on the frame.
