Jumping in to add some of our details -- our PD is Feb. 5, biometrics March 7, standalone approval in the USCIS account March 9, received SS card in the mail the following week, and the actual EAD card in the mail March 30.
Everything else (485, 130, 131) is in a holding pattern.
We received an RFE immediately after filing (2/13) for medical and clarification on some of my (USC) tax / income info. We sent that in March 12. (FWIW: I saw somewhere else in these forums that someone said if you get an RFE, then all of your applications [ie 765, 485, 130, 131] are put on hold until you respond, but not true; my husband's EAD & SS card were approved before we responded to the RFE.)
