On a multi-tap current transformer (CT), once the selected ratio is connected, is it necessary to short the unused terminals?

The unused terminals must be left open. With multi-tap CTs, as long as there is a load/burden on the chosen ratio terminals of the unit, potentially hazardous voltages will not build up at the terminals.
