I used to have to wear a brace on my right wrist and had pain in my right shoulder from typing all day. Ergonomic keyboards helped, but the two things that virtually eliminated the problem for me were switching to a rollerball or trackpad, and learning the Dvorak keyboard layout. Using a trackpad eliminated the motions that were causing pain in my shoulder, and learning Dvorak made it so my fingers didn't have to move around as much, which helped my wrists a lot.

Some other ergonomic changes that I have found helpful are to use a standing desk with a monitor arm and placing my monitor so I'm looking slightly up.
