Dark energy might be important, but I'm not 100% sure of it. It seemed like more of a background element of sorts, storyline-wise. Of course, it could be an example of the "Chekhov's Gun" technique, where something is introduced but seems irrelevent until later on. As for the Harkin thing, I think it'd be rather interesting, seeing as he has gone from good to bad a couple of times already. And as for Wrex, I definitely hope he's in the squad. He was my favorite in ME1.
