I've had some close calls with RSI and the most helpful things for me were: 1) Getting an ergo keyboard, in my case the Microsoft Sculpt 2) Remapping my keys to better match my workflow. Left and right parens are mapped to left and right shift - same for Ctrl-Braces and Alt for brackets. Mapping Caps lock to delete one word back was also a big one. Further, I have the number pad on the left to both make using the mouse require less movement in addition to remapping all the numpad keys to useful programming commands.
