Looking some more at your setup...
You will need some powerheads for water movement. I have a 55g and I have 2 maxijet 1200's. They run about $20 each.
The live rock is a good start, I have 70lbs in mine. Adding more after the fact is more difficult as it can cause your tank to go through another cycle.
Your lighting will be insufficient for anything but FOWLR and I commented on it above.
I love my AquaC skimmer and have been very happy with my Nova Extreme T5 fixture, athough if I was buying again today I would go with the Extreme Pro.
I have crushed coral, I would recommend sand.
Good luck. Remember that you need to cycle the tank and be patient. Instant gratification is something you should look for in another hobby, not this one!
