I would like to ask :

Pala

Zeal
Grief PB < how many ias must be ? >

Fanaticism aura level 27

+ 20 ias amu enough to have a good speed ?

thanks for your help

only need +9% off-weapon ias to max

Zeal out if I put correct stats into the calculator.

I searched d2r ias calculator then assumed 30% on-weapon ias.

As stated above you don't mention attack speed on Grief. But also assuming 30%, maxroll says you're good with just Grief.
