Patience Please. Ammonia is good right now and a good time for you to do lots of reading on the animals you want to keep. It is better to think ahead of time and not get incompatible animals that will just die and waste your good money.
PS: yes your rock work is looking great. Try to get it up to ~1-2 #'s per gallon size of your tank. Remember that this will end up being your main filter if and when you go full reef.
I would suggest that you start off with a fish with liverock setup and learn the ropes then move on to a reef. Keep reef friendly fish so that you don't have a problem when you switch. So a couple of clowns, a gobie or two and your set.
