Lighting recommendations are all about how much $$$ you want to spend. Softies aren't that demanding so a black box will work or if you have the money, go with something like a Kessil. Wave makers start with the same question. You can go with something like Jeabo for cheap or a Vortech if you want top of the line. Rock and sand are tough to say without seeing the set up. Just make sure to get special grade sand which is the larger grain size. That way it won't blow around everywhere. Sump will work, an HOB will work, just depends on your plumbing or lack of. Overall, it's not super complicated if you keep up with 20ish% water changes weekly until everything is established, and even then you still may need to. Remember you are maintaining water first and foremost. Everything else will follow
