So if you are included in the I-485 packet, then you are also eligible for the EAD on that basis. Since you already have a valid EAD, you do not need two at this time. However, before this one you have expires, you will be able to apply for an extension EAD on the basis of the pending I-485 on your behalf. You should also know that you should not be traveling on the F-1 visa if you are married and have i-485 pending. If you need to travel internationally, you must first obtain an advance parole travel document.
Please let me know if you have any additional questions or need further assistance.
