You can use the EA account you made for Battlefield as the account for TOR, they've merged together some time ago I believe. As for Origin and TOR, here's the quote from the Dev here:TheEggplant said:And did they say anything about installing Origin to activate TOR?

Stephen Reid said:No, you won't.SomeRandomDudeOnTheForums said:Thank you for the clarification, Stephen. I have one more question, will we have to install Origin and run it in order to play the game, get updates, etc. even if we purchase a boxed copy?
While Origin will be the exclusive digital retailer for Star Wars: The Old Republic (in other words, if you want to buy it online and download it, you?ll do so through Origin) that does not mean that Origin is required for you to access or play The Old Republic.
Origin is a digital storefront, and the desktop application is there to give you quick access to Origin exclusives and deals.
However, you won?t need to launch the Origin application to run The Old Republic, nor will you patch the game via Origin. Once the game is on your hard disk, you?ll be connecting to our servers to patch and launch the game, and Origin does not have to be running to do that.
edit: Added original question Mr. Reid was answering, for better context.
