First things first, MAKE SURE YOU ORIENT THE SOCKET CORRECTLY. You do not want to reattach this backwards. Also, you should clean up the area before sharing pics. This one LOOKS relatively straightforward, but I can't be certain because of the grime left.
Use a bit of non-conductive epoxy to glue the socket to the board in a way that the 2 pads that still look good are lined up. Then solder those two pins in. One of the remaining pins looks to have been attached to a bit of a plane indicated with cyan in my modification of your image here. In red, we see the trace that goes to the other pad.
Using a scalpel, scrape away a bit of the solder mask on that plane and on that trace to expose some copper. Then use 0.2-0.3 mm wire to solder in a jumper between the newly exposed copper and its associated pins. Not the easiest "first job," the but reward is probably worth the risk. And hey, you can't really make things worse unless you attach the socket backwards and apply power to it.
