The Wii will plug right into the yellow/white/red thing on the front of your TV that you describe.

The wii comes with ONE controller (that uses batteries) and the game system, and sports package disc. The disc has boxing, tennis, baseball, bowling, golf and a few other things. its a great disc package and will teach you how to use your system.

The Wii balance board (fitness plus) is a MUST have! its $89 new. the disc (games) will be about $19 depending on where you shop. They may have used ones at a game store if you look. It comes with a balance board disc that lets you play hula hoop, and other tight rope walks and stuff that really helps you balance. It has many great activities on the disc, and will be a great start for you.

they have many great games, and easy games to play. You can also download them directly from the internet if you have a wireless signal in your house, or you can plug a LAN cord from your router to the machine. it will update the machine, and its software.

its an awesome investment! Try to start with the basics. I got an extra controller, and a nunchuck (that hand held thingie) and a charger for the units, so I wasnt using up batteries. I hear that the batteries can last a long time, but its easier for me to just plunk them back into the charger. I dont have a charger for the balance board. The batteries last and last on that.

resort island is also a wonderful game! tons of fun.
