continuous backgrounds

[strangely]

well i'm working on a game right now and i have a background that needs to be continuous like in the original super mario, do i just create an instance where when the character leaves the room it restarts, or is there a better way.
also how do i create a camera view, like a background that is to big for the screen, and i only want to see the main character not the entire room. please help!
