Cycling with live rock is a good idea, if it isn't already cured. If it isn't then it should have plenty of die off to start the cycle. If it is cured you should go to the grocery store and buy a raw shrimp and throw it in there. Theres really no point to cycle with fish. The only thing that will survive is damsels, and you don't want them in your tank when you start adding other fish. (with the exception of chromis, they are nice)
