"Turbochargers" by Hugh Maclnnes is a pretty good book that will give you a lot of the basics. Some of it is outdated, but still not bad. Turbine sizing is tough, a lot of people rely on monitoring drive pressure and then changing housings. On gas rigs, having the turbine around the same size is popular, but diesels seem to work with larger turbines, say a 62/65 or even larger. There are about a billion theories on compounds, and I've seen everything from a 95mm into a 62mm, to a 83mm into a 71mm.
