sertra2002,
You got I-140 RFE within 40 days of your I-485 filing. From this I can guess that after receiving your I-485/I-765 and I-131 petitions, the Officer took your I-140 case to complete the prima review for your I-765 and I-131 approval. At that time, the officer felt that your company financials were needed and sent RFE.
After receiving the documents, the officer found that the documents were O.k. So he/she approved your wife's I-765 and I-131, because I guess your wife's security clearance might have completed earlier than you. (Yours might be still pending for clearance and that is the reason why your I-765 and I-131 are not approved yet)
Over all, I feel your case is going to get approved and it is just the matter of time. When they start processing concurrent cases again, hopefully you should be first in the list (If your security clearance is completed by then).
This is just my guessing and I may be completely wrong.
