Also check for any bike Co-Ops in your area as they can assist you in doing the change. As mentioned, it's not a real difficult job but there are some things that can be hard to figure out for a beginner and need to be done properly such as getting the proper spacer sizes which may need to be changed for a different stem and getting the proper tightness on the star nut to set the bearings properly. You might as well check the headset bearings as well to see if they need grease while you have it apart.
