If you mean the Xbox 360, then yes you do. There is the old one antenna version that is hard to find now but is cheaper, and the two antenna model that is about a hundred bucks or so.
On the other hand if you mean the newest Xbox 360 Slim, they come with built in wi-fi so they don't need an adaptor to connect to the internet.
You don't. If you have the new Xbox 360, you don't need a wireless adapter because it has built in wifi. But if you have any other Xbox 360 console then you will need a wireless adapter.
If you have a Xbox live Gamer profile, you can just recover it on the new Xbox. If you are not online, you will need to buy a transfer cable.
Yes, you only need to find a wireless connection and you can go on Xbox Live.
