For the tractor and five-way circular pistons (at 2:17) http://www.youtube.com/watch?v=3o6pcbhylmQ&t=2m17s are we yet at the point where they are printed as-is (i.e. pre-assembled)?

Or are their parts printed separately and then hand-assembled?

No, since the Replicator 2 can only extrude a single filament at a time, and that tractor has more than one color, it must have been assembled afterward. The Replicator 2X is the model with a dual extruder: http://store.makerbot.com/replicator2x.html
