You get them by passing levels.
You unlock all the bonus levels (five on Orb 2 TNL). These are special unnumbered challenge levels, not like the first 20 in Orb 2 or Orb 2 TNL.
You unlock them by making progress in single player.
You can unlock all levels in NSMB wii in two ways: 1. You beat the levels and get to the secret places too. 2. For world 9, get all the star coins in one world to unlock one level. To unlock all 8, get all star coins in worlds 1-8. After you get all star coins for world 9, you've beaten the game to it's fullest extent, not including points and regular coins (which don't really matter).

I don't think there is cheats. All I know is that you have to unlock levels to get new weapons.
