It is not necessary to use a 3-conductor cord, but if you do, crimp a lug to the green wire and connect it to the metal fan body using an existing screw. 
Many pre-1940 fans have a switch/speed coil setup in the base. There is a plastic-covered switch lever. If the plastic cracks off, the metal lever is exposed, causing a shock hazard. If you want, use a polarized plug (or 3-wire) and make sure the neutral connects to the switch (not the hot). Touching neutral is no hazard.
