Which to Upgrade First?

Peacebringer is mega heavy, and I'm already stretching max weight with Staff of Battle.

I'd go with the third option of Wu's Quivering and FBSS. This would make your damage/delay something around 23/23, maybe even 23/22. which is definitely going to be better than 38/40 even with a loss in Str and AC. IFS is brutally slow with no haste. Wu's/FBSS will be better than straight Peacebringer too imho.

IFS confirmed sucks. Don't every buy one over a Peacebringer
