Welcome to the mad house Seems like your making a good start but don't go to hard at it, you should be in it for the long haul.

Before buying new tires you might want to try different pressures, if you want the feeling of better rolling try 80psi. I don't believe going narrow is always the answer it's more about the weight and construction of the tire. Are you using bar ends ? They can help taking pressure off your wrists.
