Depends on how much rock you have really, when I do a new tank i move existing rock from one of my mature tanks and put that in and it allows me to add fish almost immediately. BUT I always add a ton of rock which is very important. You are quite light on the rock. I wouldnt add anything more for a bit, until you are sure the live rock that you have is processing the waste. Bacteria starter probably wouldnt hurt, just not sure how much help it can be. Like I said, just keep an eye on your water and go from there.
Wish i could be of more help......but thats the best I can do.
