So is the photon molecule, after it exits the medium, still traveling as a massless particle would; at the speed of light? I'm trying to picture complex 3d structures made only of light, as mentioned in the article, and thinking they are going to be moving at light speed... Do I have that right?

Well as I understood it isn't the photons that interacts with the other photons, it's the way the cold molecules interact as the light passes through it that changes the light course in a way that, if we would look only at how photon is traveling in the atoms, looks like it is interacting with the other photon. I may have misunderstood it, but if it works that way then any structures would disappear almost instantaneously.
