Yes - make an InfoPass appointment to find out what was entered in the computer. It sounds like very little went wrong, if anything. Your son must wait for his EAD card to get an SSN - he is not work authorized, like the K-1's are. Be sure to apply (I-765) for one when you fill out his I-485 AOS application even if he doesn't plan to work - it's free, and provides a Federal picture ID that proves he's legal, and allows him to apply for an SSN. For your wife, bring the marriage license and see if her application doesn't go through.
