First of all spihunter, I would like to be the first to welcome you to aquarium advice. About your question. Your live rock seems to be completely "dead" right? It will only become live again if you seed it with some living rock. I would suggest to buy a few pounds from you LFS
and incorporate it in with the rest of your structure. It will take a few months, but the coraline algae should start to grow and "revive" your currently dead rock. Different coral require different light requirements. I'm not sure what type of lighting you have from your planted tanks, and if they could be incorporated or not, but you will need an actinic (blue) light of some sort. The best suggestion I could give you about getting started is to read cover to cover "The Consciencous Marine Aquarist" by Robert Finner. HTH
and happy fish keeping.
