Coupled with intensive reading, which is the most effective strategy for the verbal section of the SSAT?
You should do both, but I think the word roots/prefixes/suffixes are more useful. This is just my opinion. You have to see what works best for you.
Both, by studying a vocabulary book that organizes words by roots
Any examples of books organized that way?
In my opinion, I only studied words but knew most of the basic roots (mal=bad, bene=good) and did very well on my verbal SSAT, so I would say spend more time on words but know some basic roots.

I doubt that. For verbal section, I think it would be better to grab a roots based vocabulary book designed for SAT. I would pick up something thin and concentrate on those words only.
