you have to get the xbox 360 game buffed so it can be fixed.
No.
You get a cooler for the back of the xbox
Yes. :D
The xbox 360 will put a ring around your disk if you move the xbox modem or it falls over while the xbox is on and the game is in it. Most of the time that means the game is not playable anymore.
the 2 red ring of death means that yes your xbox 360 is overheating. the reasong it is overheating is most likely because it is dirty take it apart and clean it and it will most likely work.
By hardware failure.
Get a Ps3
means no controllers are connected

It will freeze a lot. If you have a white Xbox the ring will turn red.
You can tell your Xbox 360 is overheating when the fan stays on and sometimes when there is a red ring glowing on the console.
