Excellent post, but two big omissions. First, David McDaniel, who wrote some amazingly imaginative and entertaining tie-in novels in the 60's -- mainly for "The Man from Uncle." Look for "The Dagger Affair" and "The Vampire Affair." Way, way better than the actual show. He also wrote a legendary unpublished series finale for "Uncle," "The Final Affair" -- there are graymarket copies of the manuscript still floating around.
Second, John M. Ford -- a couple of people have mentioned his Star Trek tie-in "How Much for Just the Planet," but there's another, "The Final Reflection," that does for the Klingons what Diane Duane does for the Romulans, and is a pretty fine s-f novel in its own right.
