If I remember correctly, the first time you boot the ROM, exit out of the setup, go to settings, performance, a2sd. Set one of those methods, I don't know which method is better, but you have a 50/50 shot. While you're in performance settings change your minimum clock speed to 480. Then reboot, add your Google account, and you should be good to go, with apps automatically being installed to your sdext partition. You did partition the card, right?
