Welcome to the forums!. As everyone else will tell you PATIENCE is the key in this hobby. Take your time and do it right in the first place. Your on the right track as far as everything goes.
However, do not add live rock in your tank and let it cycle. I would recommend curing your live rock in a rubbermaid container and then adding it to your tank later(this process will get rid of most of the critters that are within the rock). Or perhaps just buy Dry macro rock, its cheaper lighter and easier to work with. As far as the coraline algae goes, what you can do is for example get 15 pounds of dry rock and you would seed it with lets say 5 pounds of live rock.
I have a 46 gallon bowfront tank with about 20 lbs of dry rock and 10 lbs of live rock which I cured. My tank has been running for 4 months and let me tell you my dry rock already has coraline algae (purple stuff) growing all over it. Here is a link on how to cure live rock
