Yo! Just on the subject of sore eyes etc.
I advocate candle or other soft or indirect lighting.
In brightly lit offices, however, I have seen 'screens' over the monitor that filter out loads of UV, or whatever that stuff is, and are more 'eye-friendly'.
Other than that, pick a colour scheme other than the Windows default dark blue, and turn the brightness down on the monitor.

Oh yes, and there's a phone on the desk on my left hand side. (Forgot to mention that earlier)*BG*.
