no you have to make one then you have to connect your xbox live acc to it
Depends on whether it's Xbox live or not. You can make one free that doesn't, have Xbox live
If you account is connected to live then you should just be able to login on the new xbox. Assuming they are both 360
Yes but only if you make your XBox Live account over the Xbox Gamer Tag(non-Live). Basically, You are just converting that gamer tag from XBox(non-Live) to Xbox Live.
By disconnected, I am guessing you mean banned forever. The way to fix that is make a new windows live account, wipe your xbox, and make a new xbox live account.
if you didn't make it into a gold you wont be able to.
Make a new e-mail.
This question does not make sense. When creating a Xbox live account, you will need a email and password, the password will be saved onto your xbox so there is no need to input it every time you log on to Xbox.
Yes
Sort of. When you connect to Xbox Live, you get one free month of the Gold subscription. After that you have to buy it, or make another account.
Yes, deleting the email (Microsoft account) linked to Xbox Live will delete the Xbox Live account, but you can always buy subscriptions or gift cards again from mtcgame they have the best prices
yes to download anything on xbox live you need a silver xbox live account
