Looks good so far. It looks like you have a bubble wand in the back right side of your tank, if so I would get rid of it. You are going to get sick of cleaning the salt creep up on that side of the tank. They are better suited for freshwater tanks. You will get a million different answers on what kind of light you should get, so it's hard to give you any suggestions on which one to buy. Figure out what kind of corals you want to keep and research there lighting needs and go from there.
