As I noted on the fighunter site, I have not read The Left Hand of Darkness yet. I have read all the others you mention. I just gave a test on Julius Caesar as a matter of fact. Interesting note about that, I have always seen the play as a dark comedy through and through. Caesar is stabbed thirty three times, and is still standing after the thirty third stab long enough to say, "Et tu Brute? Then fall Caesar!" which is kind of hilarious to me. Like, seriously, Brutus? Thirty two stab wounds not enough? Then Cassius dies based on his own laziness in watching Titinius ride to meet the others and relying on the idiocy of his slave who doesn't hesitate to kill him and procure freedom. Moments later Titinius comes back, looks down and sees him lying dead. And Brutus declares he would never kill himself (based on his Stoic values) but instead asks person after person (5 in total, including Cassius much earlier) to do the job for him, and in the end has to run into his own sword as his friend holds it and looks away, effectively mocking the rigidity and arbitrariness of Stoicism. Very funny play, in my opinion.
