No, The Original Controller and the 360 one have different ports, so you cannot Use Original Xbox Hardware For 360
Just about any Logitech USB Microphone will work! Even an Xbox360 Headset will work.

The Logitech Cordless Vantage Headset will work great for chatting.

No. A wireless headset unit would work off of a blue tooth network. All equipment needed for your headset should come with the purchase of your new wireless headset. It is important you make sure you try on the headset for comfort on your ear assuring it is not to big. There are different sizes you can purchase.

Yes, in a way depending on what you question is. If the guest has a headset it should work.
