You'll buy PC games. The XBox controller can be used with some PC games as a standard video game controller.
The standard wireless controller cost $49.99 at Gamestop. There is no reason to get a cheap controller or used controller because they wear out over time. Even if you don't abuse them.
No, Xbox controllers can only be used for the Xbox. For Mario Kart Wii, you can use the Wii Remote, Wii Wheel, Wii Remote and Nunchuk, Classic Controller, or GameCube controller.
if you are willing to spend a little more you can get an adapter for wireless controllers, but a wired works the same.
The Xbox 360 controller will not work on an original xbox console. Similarly, an original xbox controller will not work with the xbox 360. Each controller only works with its respective console. Xbox 360 Controller --> Xbox 360 Xbox controller --> Xbox

Any PS2 wireless controller should be able to work on the PS1. A PS3 wireless controller will definitely not work on the PS2 and PS1, because they use Bluetooth as their wireless technology, whereas wireless PS2 controllers use 2.4GHz as wireless technology.
IRQ 1 is used exclusively for the keyboard controller.
no the Dual Shock 3 controller is Bluetooth and the PS2 does not have Bluetooth, although it would still not work for other reasons
No, the original Xbox controllers are not compatible with the Xbox 360 system.
Yes, a wired xbox 360 controller can be used on a PC as a gamepad.
The lowest retail controllers are not wireless and you need to be close enough to the xbox for the wire to reach which is usually around 10' Otherwise you will need to look into used controllers for lower prices.
