Is it only a coincidence that the moon's rotation matches its orbit around the Earth (which is why we only see one side)? Will that rotation change, or will someone ever be able to see the back side of the moon from Earth?

No it's not a coincidence, it's called tidal locking. The larger object essentially induces a drag on the rotation of the other, until its rotation synchs up with its orbit. All the large moons in the solar system are tidally locked, and Pluto and Charon are locked with each other.
