Infinity ward has not developed a way for 2 people 2 go online for any console, you can play split screen together but online no
There is almost no point just sign in all 4 controlers on the same XBOX 360 and Pow! you have 4 player
you cannot unlock them you have to buy them on PSN or LIVE Marketplace
There are no avatar awards for Modern Warfare 2 on the Xbox 360. There are, however, Modern Warfare 2 themed items available in the Xbox LIVE Marketplace. To find them, first you must enter the Avatar Marketplace. Then, select Game Styles. Look through the pages until you find Modern Warfare 2, and from there you can buy what you wanted for a set amount of Microsoft Points.
Xbox live shut it down because someone was hacking it..
Sadly... no. You can play Special Ops multiplayer, Xbox Live and split screen. And you can play Xbox Live, Xbox Live but not split screen

Unfortunately no, you can't play multiplayer on Call of Duty Modern Warfare 1 or on Call of Duty Modern Warfare 2 on the same screen. But on Call of Duty Modern Warfare 3 and Call of Duty Modern Warfare Black Ops you can play multiplayer on the same screen. There is an new Call of Duty Black Ops 2 coming out soon though, so I expect that to also have that feature, since its newer.
both
Depends which modern warfare game you mean if its the first one you cant play co-op but on modern warfare 2 you can play with another person but only on special ops. You will need to get a second controller, use system link or play with people online(Xbox live/PSN).
You can play 2 players on Special Ops missions and you could also party up with your friends on Xbox Live.
Same
You need more than an ethernet cable you need to have Live Gold membership
In Xbox Live i say no but the campaign is cool
the best map for xbox live on the game modern warfare 2 is either favela or rust.
