you need to decide what take you want to keep,before you start buying.
that being said What kinds of corals do you want to keep? In my 46 bow tank i was using 1 korali power head and was barely getting enough flow for sps. Lighting i would say buy a nice t-5 fixture or buy Led lights, or make a combo like me. for the overflow there are tons of ways to do it, but first decide if you wanted it drilled or not. I think city pets and a few members have drilled tanks in the past. If you don't drill it then look at the crq overflow box.
Since you striped for cash, save every penny you can get! Try doing work for neighbors. I mowed my neighbors yards and was getting 100 bucks every 2 weeks, of course half went into my savings but still.
