Lighting is an important part of your office set up, as poor light or glare can cause headaches and even contribute to repetitive stress injuries (if you find yourself leaning forward or to the side to see the screen, this can take its toll over the days and months). A neat little lamp I found looks like it would work well for lighting your work area. The Soon Desk Lamp, designed by Tobias Grau, has adjustable vertebrae that makes it extremely flexible, and light runs all through the "spine" of the lamp. It comes in clear or orange plastic and can either sit on a desk or clamp to the side.
