Why would i want Amulet of dark whispers?The mainly & only reason for 1H is Infantry Training.
If you want to go Light (or 2H) then just snag the Amulet of Dark Whispers (or spend 7 skill points getting Battle Rage).
You might also want to experiment with a Hatchet (later, Tarand's Hatchet) instead of a shield and see if you like the the higher DPS albeit coupled with taking more damage.
