Depends on what kind of addons they are. You don't need Cataclysm for alot of them, though.
You have to find an addon first that is supported by cataclysm. Then once you have one you put it in the "Interface" folder in the world of warcraft folder. There will be a folder in Interface called "addons" thats where you put the addons. then before selecting your character when you are almost in game you need to click on manage addons in the bottom left corner and make sure they will be on. one good place to check out for addons is the curse addon site listed below.
Some of the more popular addons are:Boss Encounter ModsDeadly Boss ModsBigwigsBag ModsArkInventoryBagnonOneBagAuction ModsAuctioneerAuctionlite
Considering WoTLK is 18 GB Normal, i'd keep atleast 25 - 30 gb for catacylsm inclusive of addons
First and foremost, to become a Worgen, you need to have an account that is paid up to Cataclysm. If you did not purchase the Cataclysm expansion, then you can not be a Worgen.
It is the expansion pack that comes after Wrath of the Lich King. You do not need to purchase the CD/DVD to play as you can download the client which allows you to play as you are downloading (once you download enough of it). Although you do not need a Cataclysm account to play the basic WoW, you do need it to take full advantage of all the Cataclysm features, zones, and races.
Cataclysm Patch.
Yes. You have to have the first WoW and all the expansions leading up to Cataclysm. You don't need to buy The Burning Crusade anymore because it comes with the first WoW, but you do have to buy: Wrath of the Lich King and then you can buy World of Warcraft: Cataclysm
