Internet connection!! wire v/s broadband or Wifi?

Cheapest internet will be dial-up. That uses your phone line to connect to the internet, it is also the slowest. Broadband or cable internet is going to be slightly more expensive but it will give you decent internet speeds and it won't interrupt your phone lines. Wifi only matters once you actually have internet set up, so don't worry about that just yet. If you can afford it go the broadband/cable route.
