IMO, yes.  If they run cold all the time, they burn more fuel and wear out
quicker.  Replace the thermostat with a 180F unit (or possibly the gauge is
wrong).

Plug temperature has nothing to do with coolant temperature.  Unless the
plug tip indicates it is getting too hot (or not hot enough), leave the
plugs alone.  The thermostat is what controls coolant temperature
(hopefully).
