Thank you for your question! You don't need to have Xbox Live or a subscription, but you will need to have your console set up with internet access as this is a download/digital copy of the game. You'll need to be able to download it.
It's basically the same game, but it has some extra features and minor graphics improvements. It also includes the Stop-n-Swap mode that was cut from the original game.
No at the top it says no sorry
It’s a digital download just like a dvd you might buy that has two or three versions of the movie
