You got it. The recessional velocities come from the expansion of the space itself. There could be things far enough away that they are receding from us at faster than light speed. We will never see such objects, since their spectra are basically red-shifted to zero energy.

I took special relativity in college, but not general relativity. Consequently, I have some unanswered question about the expansion of space. How can one distinguish between an object's velocity (movement relative to space) from space itself expanding? Similarily, general relativity accounts for gravity due to space curving, but curving relative to what, meta-space?
