Are you talking about two multi-DOF hands, or two separate multi-DOF manipulators with hands at the end?

Yes there are some gaps in the documentation. You should read all the normal ROS arm_navigation tutorials, and also the ROS industrial ones. Also use Google to search for everything related to arm_navigation, joint_trajectory_action & follow_joint_trajectory.

If you followed the tutorials, you should be able to load your robot model in the planning warehouse viewer, plan trajectories, smooth them and watch the trajectory.

Once you've got that far, you need to load a node like follow_joint_trajectory that receives the trajectory messages and sends it to your controller. If you're using Gazebo then you might be able to use the ROS/PR2 controllers for following the trajectory and controlling the joint positions.

Feel free to contribute your own documentation :-)
