Actually, it's the other way around. Most (perhaps all) of the speed that it is heading away from us is because of the expansion of the Universe. To give you an idea, there are only a few galaxies that are getting closer to us, Andromeda and the Magellanic clouds, and they are all right next door to us so that the expansion of the universe isn't fast enough to push them away from us. Every other galaxy in the universe is getting further way from us because of the expansion of the universe.

so in rough terms, would it be fair to say that overall we're separating from these distant galaxies, whose 13 billion year old photons are just now arriving, at approximately .9c, and that maybe .1c or .2c of that .9c is because the universe is expanding?

You can safely ignore Eugene. The problem with the theories that Eugene is talking about is that none of them can create a stable universe. If c really was variable then the theories say that atoms shouldn't be stable.
