Well, as far as I can tell, there is no consensus opinion on wrist pads or support devices. About all that I can say for a fact: one of the later stages of physical/occupational therapy is often weight training, to build up all your muscles. If you've got strong enough arms, you should be just fine without any supports, GIVEN PROPER POSTURE, rest breaks, etc.. Chair arms are another one of those weird things. The majority of chair arms are all wrong for typing. Some of the really expensive chairs have height-adjustable arms with nice squishy padding. I personally can't stand any hard-plastic or metal chair arms. Also, you mention "a neutral position" for your wrists. I hope you realize that a truly neutral position would have your thumb significantly higher than your pinky -- a handshake is a neutral position! Remember: wrists bend in more than one direction.
