Mechanics and Fixing Any Questions Answered

Based on the Campag that came off it, I guess the red spacer goes behind the freehub and onto the wheel bearing.

The big seal is already in place, so that's a spare.

Does the smaller seal get pressed into the outside of the freehub? Metal side up or down?

That all sounds right, although the smaller seal seems like the internal hole is too big for the axle, maybe it's the camera, if it fits then whack it in metal side in, if not check it's not for the other side of the hub then throw it away and pretend you never saw it.
