Can you guys give me some tips and recommendations based on what I have come up with so far

If it's one thing I've learned, it's to never go over 1/2 of your tank height with rock, or you'll never do your corals any justice with room to grow and you'll be banging into them and breaking pieces with your elbow all the time. Knock a couple rocks off each side and that's what I would do. It's nice to have some open water overhead for schooling fish and some "air".
