For Earrings you have 3 good choices I feel
Earring of Wise Traveller(Fornost: Water)/ Red Huron's Putrid Stud(OD: Disease): 150 Will, 768 Tactical Matery & 384 Crit.
Blackened SIlver Earring(BfE): 150 Will, 384 TM, 384 Crit, 211 Morale
Although there are others I think these 3 have the best stat distributions.
Necklace I'm less clued up on. I went straight from Gold ToO one to Gold Erebor Recipe drop.
But I'd suggest
Pendant of Shed Blood(Library) 150 Will, 38 Fate, 768TM.
