The conventional interpretation of the red-shift is the Doppler effect, but other ideas are possible. E. A. Milne had a cosmology in accord with the Hubble effect, but in his model the universe was isotropic and time- invariant (on a large scale only). In any case, you don't have to worry about faster-than-light. The injunction about objects not exceeding light speed applies strictly locally; if you were to travel out to where the "horizon" appears to be and remain relatively stationary, you would see exactly the same situation that you left back home (the horizon "recedes").
