As jbchybridrider said, you might check out bar ends for additional positions for your hands and wrists when you ride. Personally, I'm very fond of the Ergon GP2 grips with integrated bar ends I added to my Fuji Absolute. I would also recommend carrying a small multitool to make adjustments to those grips and bar ends when out for a ride - is this better than that, and so on...
Also, I'll second those that say to experiment with different pressures in your tires. As long as they're in the range recommended on the sidewall, you're good to go.
