So that several joints could be hooked up to one servo,
I would use a LilyPad Arduino USB as this particular Arduino would fit in your palm
You seem to be focusing on disabling servos (or joints) rather than making them work. It seems to me that making them work is the problem. I can't imagine why you would want to stop it working, but if so just disconnect/switch off/disable whatever part you want to stop working.To make it work you need to have a signal generator capable of controlling the position of as many servos as you need in your solution. Arduino could be that signal generator if you like. You would need some controller to define the movements that you wanted to achieve i.e. how the servo positions change over time. There are lots of different ways to achieve that, some that can be done on the Arduino. Have you decided what you want the robotic hand to do?
I just want the fingers to move on the hand

Are you going to have a huge bank of potentiometers (connected to what)? A sensor glove so that it mimics a real hand? A hard-coded sequence of movements? Something else?
Good - that eliminates a lot of potential complexity to provide input devices and controllers.
the amount that your fingers can flex naturally without force against them is 180 degrees
