I don't really have problems with RSI nowadays, but years ago I would be at the computer even more.
One helpful thing is switch the mouse between hands every few minutes. Your hand gets a break if you're moving the mouse a lot. I used to have a normal mouse at work and I bought a trackball for home, so that the hand muscles used would be a little different.
Someone in this thread mentioned Jamie Zawinski and his advice is to not ignore pain. So if you are typing for an hour and your right hand starts to hurt, stop using your right hand for a little while (as long as you can, really).
