I said two bulbs might be good for some fish and an buble tip. Adding coral could change the equation. This is a broad generalization and there are defnitely exceptions but much of the soft coral doe sfine with lower light. There are also hard species that are found deeper and need less light but these are not usually as readily available in the hobby. I decided to skip an anenome because they can move around and knock over corals and even get stuck in powerheads.
LR is the best filtration and if you can add a
sump to your system that will help stability by adding water volume. Besides the
LR you will want a
skimmer. For your size tank without too high a load I would reccommend a AquaC Remora
skimmer. I have one I used on a smaller tank and it worked great. Yes there is lots to learn (and lots to buy also)! If you havent done so you should download the early podcasts starting with episode 1. They will answer a lot of beginner questions for you. A good book or two will also help.
