For solo RT albums I would say that the best are:
Mirror Blue
The Old Kit Bag
Rumor and Sigh
I am also very partial towards You? Me? Us? but that might not be a good place to start.
Also, there are a number of compilations that are very good (Action Packed, Shoot Out the Lights) as well as tons of great live albums, almost any of which would serve as a good introduction to RT's work.
