What your looking for is called a no cd crack.
Read my answer under the question How do you play a PC game without the disc in the disc drive? on this site.
Yes just buy the download otherwise the console needs the disc to play the game
No you need the game disc to play the game unless it is a download. You would not be able to play without the game disc as it does not store the complete game.

You need the game disc
It is possible. You have to download a crack, which makes it possible to play the game without a disc. But this is illegal.
