There is an econimical way to buy things, watch the for sale forum and get things used, a lot of things are near brand new and will last nearly as long as if it was brand new. A good deal usually comes up with powerheads, pumps, lights and skimmers. With regards to the bulbs you may need, take one into a LFS and see what they think it may be (make sure you can return the bulbs if they aren't the right ones!), you'll probably want 3 50/50 bulbs in your setup, it'll give your fish nice color and allow you to keep some softies (zoas, gsp....). Keep us posted.
