All the recent discussion of GR has generated a question in my mind. Can
anyone direct me references regarding the 2-body problem in general
relativity, ie. the evolution of the metric and positions of 2 "small",
isolated masses?

I think what you want is the equation for "geodesic deviation," the
separation between two neighboring geodesics. It's given in any of
the standard texts under that name -- the one I happen to have open at
the moment is Foster & Nightingale, A Short Course in General Relativity,
pg. 113, ff. (Second Edition, Springer-Verlag, 1995).
