The power went out while my computer was in the middle of a long render. All is
not lost, since I've been meaning to try out rendering on multiple computers.
Eventually I'd like this all to be automated. So how do I get Pov to exit once
it finishes generating radiosity data?

No way - POV-Ray won't let you go without a main render. You can use a
reduced resolution though, running this pre-render with "always_sample
on", effectively using it as just another pretrace pass.

Does focal blur affect the radiosity data? My guess would be no. And how much
smaller is an acceptable resolution to generate radiosity data for the main
render?

In some sense focal blur does affect radiosity data: You potentially get
a better sample coverage, because more rays are shot - and from slightly
different origins. So as a result, this may force POV-Ray to take
samples at places that would be missed otherwise. Other than that, there
is no effect on radiosity.
Thinking of the "main pre-render" as an additional pretrace step, I'd
suggest a resolution of (roughly) 2/pretrace_end in whatever dimension
is larger; the other dimension should be chosen according to the
intended aspect ratio of the main render. This way, you indeed mimick an
additional pretrace step (so you may choose a larger pretrace_end in the
first place).
