Your key will upgrade the account itself. Anything you need to load up is going to be machine specific. So if for instance, you play on two machines (laptop and home pc) as long as they have the software loaded and you have the key enabled, you will be able to play your account on either machine.
BTW. You will need to load using the CD in order to have access to the Burning Crusade as well.
Here is a notice we posted up yesterday in a thread-
“It will be necessary to have a Burning Crusade CD and a Burning Crusade authentication key in order to play The Burning Crusade expansion. There is content on the Burning Crusade CD that will need to be installed that is not included in the patches we have recently released. Each account (in the event multiple are owned) will need their own copy of The Burning Crusade expansion to install the additional content, and be upgraded with the included authentication key.”
Does that help?
