I have found that once the ammonia is zeroed and the nitrites are dropping off, the cycle is well on it way and will finish fairly quickly. I'd still wait until the nitrites are unreadable or nearly so before adding any livestock. I wouldn't panic on the Ph too much until it is fully cycled. Once things have settled down, do a large water change to help get rid of the nitrates, then add buffer if needed to raise the Ph. While the rock is curing and the tank is cycling, messing with additives is really pointless because the system isn't stable yet anyway.
I have some LR curing for my FOWLR tank that I got with the bulk shippment from J&L, and it is at about the same stage as yours. I don't plan to add it into the tank until I am certain it is fully cured since the tank has livestock in it that I don't want to put at risk. I expect it will be at least a couple more weeks, if not longer.
Just have patience and enjoy the process. Its actually fun to watch for hitch hikers that should be starting to appear soon.
