Magma's advice to put all lights on one breaker is good advice. Since you have 4 breakers you should have no problem dedicating one to lighting only. I found the GFCI receptacles couldn't handle my halide lighting which is why one of my breakers is GFCI instead of the receptacle. The GFCI breakers are about $100 each where the receptacles are $20 each. My understanding is that you only need one GFCI receptacle per breaker to protect the whole breaker, but check with an electrician!
