Looking good so far! Sounds like you have researched a bit and you're on the right track. True about the lights tho, not a lot of coral is going to grow under what you have now. How deep is the tank? A lot of people would recommend LED
because they don't give off much heat, consume less power and you don't need to replace globes like you would a T5 unit. T5's would be cheaper initially but having to replace globes every 6months or so. Either way you need something like 12000k for coral growth. Most people's lighting schedule (its different for many) is roughly 8 hours of 'daylight' with a couple of hours either side of 'night' (blue) excessive amounts of light can promote algae growth.
I am by no means a lighting expert so i am sure someone else can offer an opinion too.
I would recommend investing in a refractometer, it's far more accurate than a hydrometer. Also a salt water test kit is vital to check your water quality. Where do you get your water from? That's the most important life source in your tank!
Have you been monitoring the cycle? How far along are you? It is worth waiting before you add corals, just until you get your parameters stable and you get the hang of the maintenance.
You got a filter or just the live rocks? Either way you will need to get use to weekly water changes. Beware tho, saltwater is addictive!!!!
Any other questions just ask
