Also, a much broader and more basic question that I admit to having never been clear on, what determined the distribution of velocities of the baryons that formed after the big bang? How would thermalization work with particles that don't interact?

Dark matter viralizes through gravitational interactions. That brings the initial overdensities into the roughly spherical halos composes the dark matter around galaxies and galaxy clusters.
