  You also need to ground it (you should be doing this anyway for electrical safety).

    Should there be a resistor (100K? 1M?) on the connection between shield and ground?

      I am not an electrical engineer, but AFAIK no. You want your ground path to be the favored path, rather then say, a sweaty human hand if there's a short.
