So right now i have a 75 FO aquarium with a wet/dry overflow filter. I have a protein skimmer and a uv steralizer hooked up. I plan on gets some live rock and doing some low light corals so i know i need some lighting that's at least 150 watts (2 watts per gallon) i wanna go ask cheap as possible (have no problem buying used equipment). So my questions are

1. What else do i need besides the lighting. and what are some suggestions for cheaper lighting

and

2. not including live rock how much is everything going to come out to cost me?

Well to start making a reef tank can easily pass $500. If you want to start a reef you will need to first test your water to seem what you have, then buy some kind of calcium and other supplements. How deep is your tank? This will help in determining what kind of lighting you will need.
