Pencil urchins will eat everything, not one of the reef safe species. As for removing it, just reach in and pick it up, gently, of course. Pencil urchins are one of my favorites. We have used them for educational programs here for many yrs, one of the few that the kids can safely touch and handle. Mostly the kids get a kick out of the feel of the urchin walking across their hand.
As for the lighting suggestions, badxgillen had some good ideas to offer you.
While I understand the frustration, one of the first rules of keeping a marine tank is to understand that its expensive. There is no way to make it cheap and make it work all at the same time. The equipment is expensive, maintenance can be expensive... and, depending on what is being kept and how it is set up, it can also be very time consuming. The smaller the tank the harder it will be to keep stable and healthy.
In situations where people try to make it cheap, most end up spending more money than ever when things start to die. When the tank is full of live rock that averages 8.99/lb, corals that can range in price upwards of $100 each... even "cheap" marine fish are going to run into the $6 - $10 each range, death gets expensive.
In the case of the lighting, fires are expensive too. I am not telling you the things I have, suggesting the things I have just to spend your money. My goal is to see healthy animals and safe hobbyists. I have been working in this industry long enough to know the kind of damage that can happen and how simple of a thing can cause it. Trust me when I say, you really don't want to find out first hand.
