WRONG, the redshift is just the means used to tell how far away they are.

Correct, but it was this redshift that showed the Scientists that the
Universe was expanding, and the redshifts showed the scientists that the
expansion was going faster than they thought.
Which led them to the fact that the universe is expanding quicker than the
speed of light.
http://en.wikipedia.org/wiki/Redshift
In particular, Doppler redshift is bound by special relativity so v c is
impossible while, in contrast, v c is possible for cosmological redshift
because the space which separates the objects (e.g., a quasar from the
Earth) can expand faster than the speed of light.[19] More mathematically,
the viewpoint that "distant galaxies are receding" and the viewpoint that
"the space between galaxies is expanding" are related by changing coordinate
systems. Expressing this precisely requires working with the mathematics of
the Robertson-Walker metric. [20]

Their light is so old that instead of it being blue as it was, it has
shifted to the red and this does NOT mean it has gotten faster.

Correct, just that the space between us and what we view has expanded
quicker than the speed of light.

The speed of
light has always been the 186,000 mps but light does shift as it moves.
You
look at M31 and you'd find because its heading right towards the milkyway,
it's light is more blueshifted instead of redshifted.

Correct, but there is something at play that appears to be going faster than
the speed of light, to account for the size and expansion rate of the
universe.
Way over my head, but I enjoy reading about it.
