If you have the donate version, you can go to settings and create a zip that is flashable in recovery. After you create the zip hit the menu button, choose batch, and choose backup all user apps+data. Flash your Rom, after you let the Ron boot up once, reboot and flash the titanium backup zip. This will reinstall titanium. Go to batch and choose restore missing apps+data and your done. You might as well go ahead and get the donate version because if you don't have it you have to click install for every app. With donate version, it just installs them without you having to click everytime. Make sure usb debugging is enabled or it won't work correctly.
