Ias needed on Griefz and why and also what kind of Amu does a charge smite use ?

ias needed depends on your fana lvl, best use an ias calculator

Highlords or 2pal dual stat life res ammy.

Id use hoghlords or angelics, u want to make sure i connect on the charge with high defense characters and if chasing a sorc or necro use highlords. The 2 pal wit adds i wouldnt use unless you are incorporating foh and wearing enigma.
