No. Xbox live sliver membership is free. You will become a silver member after your gold membership has ended.
When you create an account on your console it automatically becomes an Xbox Silver Account (free account). But you can purchase an Xbox LIVE Subscription which you can't get for free.
A silver membership will allow users to download demos, games, etc from the xbox marketplace.
Updates will need an internet connection. You can just hook up your Xbox 360 to the internet, sign up for a silver membership and you will get updates.
Xbox Live Gold membership is 49.99 for 13 months but i have heard there is somewhere if you order it on the internet that it is 10 dollars cheaper. Xbox Live silver membership is free but you are unable to play online or chat with friends.
Yes, one can have more than one account with membership (silver and gold).

Download demos, buy games, play games, private chat with friends
Membership is linked to your profile.
Original xbox games work on only elite 360 or higher, not arcade. If they work on your 360 then they should have live as well. I haven't tried yet though, I still have a silver membership.
