Great list. As an Honorable Mention, I would like to o add this: Though "Earth: Final Conflict" became unwatchable after season one, the first season is, I think, among the best SF on television. And the best first season episode was "Sandoval's Run", which provided a look at the heart-achingly grim cost of devotion to the alien "Companions".

I a subsequent ST:TNG episode in which a visitor to the Enterprise told Picard how much he enjoyed reading Picard's book documenting his "Probe Life". Though it was an explicit reference, it is the only one I know of.
