Duplex is worth while for more accurate cam timing, but i never bother with them as i've had no probs with simplex chains.

Leave the standard drive pully on, it is also a vibration damper for the crank, putting a lightened one on will do nothing for preformance, but might introduce a few new vibrations...

Unless its a vernier type, a duplex will not give you more accurate valve timing
Unless you do 30,000 miles or more
