Yes. The Burning Crusade is an expansion pack, meaning it takes the original and adds to it.

You don't have to have a special account, but you have to of made a regular World of Warcraft account and have the Burning Crusade with an unused authentication key.
Yes, the Night Elf race is an Alliance race. You do not need Burning Crusade to be a Night Elf. It is included with the "vanilla" version of World of Warcraft.
If you want to have more fun than you already do then, yes!
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.
No, the Burning Crusade is the first expansion to World of Warcraft and does not require any expansions before it. The Burning Crusade is included into the basic WoW now so you do not need to buy that, just the basic WoW.
Items do have sockets in world of warcraft. They were added in The Burning Crusade expansion and you need a jewelcrafter to cut gems for the sockets.

12.5 gb needed for installation
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.
I personally think that World of Warcraft: Burning Crusade beats every expansion, but if you want to play both you need to get all the expansions. You can always make characters and level them to maximum level to 70 (Burning Crusade level cap) and do only dungeons and raids specifically out at that time!
Yes, it is an expansion game for World of Warcraft. This means that you must have World of Warcraft installed on your computer to install World of Warcraft the Burning Crusade(http://wow.igxe.com/). All of them need the original game in order for them to be played, though I do not know if the original games come bundled with the newest expansion packs or not, but I think that anything's possible.
