I don' recommend sockets for the output transistors. That's a disaster waiting to happen (it might lose contact) and could fry your headphones. Just solder the transistors to the board after making sure you got the orientation right.
I am not sure what you're trying to do for the switches. If you want an input selector for two sources, and output selector for two pairs of headphones, then all you need is two DPDT switches. You don't need to switch the ground at all.
