I would recommend this:
File AC-11 and change your address info of your I-485, EAD and AP with TSC by calling 214-381-1423 and talking with an IIO. I know it is hard to get through, but you know that is the only way to make sure you get it right. If you have an attorney, then he/she should be able to fax your address information to TSC. One other point, when you file AC-11, make sure you file via a certified United States mail and keep that receipt, that will be the proof that you file for address change, in case anything mess up along the way.
