Step 2: Patch WoW, if you enter a random user\pass even if it doesn't exist it should let you patch up to the newest version. At the time of this thread it's about 450MBs of patches.
Use this direct download to get up to the latest version.

Step 4: Go into your WoW directory and open realmlist.wtf in a text editor(Notepad works). Change it so this is all that is in it without the quotes: "set realmlist wow.x10gaming.com"
Step 5: Open up WoW and create a characters, you should be set!
Will update later with a Burning Crusade DL.
