I started saltwater tanks on a budget too a few years back. It is kind of a difficult thing to do. Like somone above said, you technically don't have to have live sand if you don't want. Bare bottom tanks can look stunning. But then there are some invertebrates such as ness nassaurius snails (my personal favorite) that you cannot keep because they live in the sand. As for lighting you really don't need anything special if it will be a FOWLR tank. But just an f.y.i if you decide you want to turn it into a reef you will need a better than average light to compensate for the depth of the tank. And for a power head you can get a good one but still pretty cheap for around 40 or so before tax. I just saw a hydro power head for 40 yesterday at my lFS. And there is no need to drill holes in your very first saltwater tank. I would stay as basic and simple as possible to learn the equipment, what it does, and the benefits of it. I still do not drill holes in my tank or run a protein skimmer and my tank is doing extremely well. And research the different types of filtration too.
