If you are using the World of Warcraft: The Burning Crusade cd to install the game, then yes, it needs the internet as it will have to go online and update the game client to the very latest version of the game. This is done automatically.
Only if you want to create a dranei or blood elf, level past 60(70Max.), or go to the outland. Burning Crusade Is An Expansion For World of Warcraft.
Nope you will need the burning crusade expansion installed before it will allow you to install WotLK.
If your WoW account got banned and it is permanent then you will need to buy a completely new account from a retailer like walmart or bestbuy and if you wish to have The Burning Crusade enabled on the account you will have to upgrade it which can be done online now I beleive. But you will need to upgrade the account again. In addition: you also have to purchase a new burning crusade key
You cannot end a Burning Crusade trial, but why would you need to?
