I have a 55" rear projection big screen TV, Directv Dvr box, Wii, PS3, Laptop, and a Desktop that id like to run off 1 grounded outlet with a surge protector. The only thing is, is that its all on 1 - 20amp breaker. Is that too big of a load and can anyone offer suggestions?

You should be fine with this load on a 20 amp circuit.
