I did much as Kbarkamian. I bought two external 2TB drives from Other World Computing. I copied my iTunes folder to one of them using a FireWire 800 connection. I then daisy-chained the second drive to the first and made an exact copy using SuperDuper.
Then I opened iTunes with the Option (alt) key held down. iTunes asked me to choose an iTunes library and I directed it to the one on the first 2TB drive. From then on iTunes has opened automatically with this library.
Whenever I add new music to my iTunes library, I back up the changes to the second external drive using SuperDuper.
