Yeah, that is always a good idea. As in ensuring the tank is fully ready before adding live stock. Once it is ready though, then you are all set to do whatever. Case in point, my first aquarium after the cycle was completed I fully stocked it with five fish and corals, and it was/is a nano. I did have to tear it down as I went on holidays. Just finished re-cycling it within 9 days and stocked it with four fish again, the same residents as before the move (I did buy and sell a few before ending up with these four).
My phosphates is high so I am avoiding corals for now, once I figure out what to do, corals will be back in.
In cases where you have dry rock + uncured live rock which means a lot of die-off, you may not need to initially add any sort of organics. But I tend to bombard my aquariums initially with plenty of food anyways, promotes the growth of beneficial microbes.
Case in point (again), I feed my fish heavily, but ANN is unnoticeable.
[EDIT]
Though, I do have Marine Pure. If you want to not worry so much about ANN, it is good to have a block or the likes that will handle most of the filtration required. Live rock would only then be decorative, and you can use as much (or as little) as you like. In fact, my aquarium is live-rock-less lol. Except for whatever is attached to corals I guess, but otherwise.
