Couldn't Fett have been listening in on Han and Leia's conversation and therefore know exactly what they're up to? It might be cool if we could hear Han and Leia still talking to each other when we are inside Fett's ship, over his radio or whatever, so the audience knows he's been spying on them. Dunno where the audio for that could be sourced from though... Maybe deleted scenes? Anyway, then you could leave the hyperspace jump in because we would know that Fett knows Han & co.'s plan and that he is going to meet them there. Also, when we see Fett in his ship, he's messing with controls which could be the "navi-computer" or whatever to jump to light speed.
