And what really makes my head spin: If this galaxy is moving away from us at the speed of light, and has been doing so for almost the entire age of the universe, doesn't that mean that it (and all observable universe) started out from "our" position, even though the big bang should NOT be considered to extend from a central position?
Yes, in that the universe was a point at the beginning, therefore 'our position' was at the center of it, as was the position of everything else in the universe. It might be more accurate to say that instead of this galaxy moving away from us, the space between our galaxies is expanding. All of space is expanding, with gravity keeping structures at the galaxy/local group level close enough together that they do not expand themselves.
By the time our universe is 20 billion years old, that galaxy will be 19.4 billion light years away. The above math would then result in the galaxy moving away at a speed greater than the speed of light. I guess we'll see time moving backwards?
Nope, actually we won't see anything at all, as the light emitted by this galaxy will never be able to reach us. The light from this galaxy will redshift to a greater degree until no more information reaches us.
