The best route is indeed through KDL. And you're right, KDL is lacking
documentation, although there are some small examples on the KDL
homepage <http://www.orocos.org/kdl>.   For an example of Jacobian
usage in our ROS distro, take a look at the
cartesian_wrench_controller in the robot_mechanism_controllers
package.
