Hello! I am trying to wire a normal two-way switch to a light socket plugged on the wall (120W). I just want to know exactly how I am supposed to wire the switch sing I have 2 wires coming from the wall plug and two from the light, considering there is only two places to "connect" on the switch. Help would be greatly appreciated!

It is usual to switch the "live" or "hot" wire. The other wire is "neutral" or "ground". If the wall plug has one blade wider than the other, the wide one is the hot one and will have a black wire connected to it , if it is color coded (USA standard). Connect the hot wire to the switch and one of the lamp wires. If the lamp wires are color coded, use the black one. The two other (white) wires are connected together.
if in the uk, from the mains, black is connected the the blue on the lamp, red is connected 2 the switch nd the brown from the lamp is connected 2 th switch
no problem, it's common enough to find outlets that are wired wrong. sometimes things have been wired wrong "upstream" also, always good to check with a meter or one of those plug in checkers with the 3 neon lamps.
