Why would Batman go after Superman? That's a good question. As we have seen in the comic books, they both are good guys. Fighting for justice. They just have different methods.
When it comes to the Batsuit - like many I've heard there is two costumes. But ideally I would love to see a scene in the Batcave, where you see many other costumes - some in glass cabinets (like the fallen Robin), others laying discarded on the floor. And of course a crucial scene, a weary seasoned Bruce Wayne feeling he is forced to don the costume once more to confront this new alien.
