This is saying that heat lightning is ordinary lightning that occurs too far away from the listener for it to be audible–so far that it cannot be heard. It is lightning that occurs at a distance that is too great. “a distance that is too great” is semantically equivalent to “too great a distance.” For example, if I say “I am too fat a man to be eating this much,” I am saying “I am a man who is too fat to be eating this much.”
This is saying that the valuable instruments in this display were crafted by artisans who were famous back then but have been forgotten (are not famous now). There’s no reason to think that “long since forgotten” modifies “instruments”…at all.
It is illogical to say that there is no story that is more dramatic than Hank Aaron. You would have to say that there is no story that is more dramatic than the story of Hank Aaron. Instead of repeating “story,” you could say there is no story more dramatic than that of Hank Aaron. “that” is singular, and in this case substitutes “story.” If you are referring to a plural noun, you would use “those” (e.g., “There are no stories as dramatic as those of Hank Aaron and some other guy”).
