Sounds like you have a bigger problem than just a bad SIMM socket.
You state the system doesn't go to sleep when you close the lid or access the menu Sleep instead it abruptly shuts down. The fact your USB devices are burping because the system shutdown incorrectly is to be expected.
The first question I have does the system react the same way when you don't have the USB devices connected? If so the system has another problem that is tied into your memory issue. If the system does not shutdown incorrectly then your USB hub and/or one of the USB devices has a problem as it's drawing do much power.
Question two did you get your system wet or could it have been sat on or twisted? A good clue does it rest on all four feet on a level surface correctly or have a dip in the bottom cover? In either case you may have a short.

Remember to Air's are very tight inside and have very little clearance. You may need to open up the system to check things out. Look around the controller chip for water damage or bent cover.
