As for gay characters in Star Wars; when JJ Abrams said there would be openly gay characters in future installments I remember Kieran and others saying that JJ had said the exact same thing about the new Star Trek movies and nothing has come of that so far.
I would love it if Poe is gay but Finn is definitely straight, or at least attracted to Rey. I've also heard that there's going to be a new character in the next film that is an Asian woman who is Finn's love interest. Oscar Isaac was definitely talking about Finn when he said that he was "playing at romance with someone" in his interview on Ellen, but I'm highly skeptical they would actually have the balls to confirm Poe as gay in the movies. If Poe is gay it's more likely that they'd acknowledge in the comics but leave it ambiguous in the movies.
Sorry that I'm not more optimistic but at this point I've pretty much completely given up hope of seeing any LGBT representation in any popular movie franchise.
