Im at lvl 70 act 5 NM

what gear should i try before hell?

Black runeword?
Treachery wt NM or Hell? Need Lem

probably treachery
black is nice for bosses
gore rider i assume
strings is ncie for dr%
decent merc stuff for a bit of safety

Black for boss
What for normal monsters?

not really sure tbh im bad with kick assas

Thinking ablut respec to only trap asn
Too low dmg

u could do a hybrid tho should work alright

Is mf better with p8? Or no difference?

mf is Always nice
but if u allowed urself to farm bosses on Players 3 u shoud do that
the biggest jump in Drops is at Players 3
p4-8 is big yea but the time u take to kill the boss is really shitty on most of Chars
and as a pure trapsin bosskilling is shit anyways i usually stick to pindle eldricht shenk before i go to hell

Ok
I will go eldrich shenk and pidle to mf a bit

One more thing

If i use 2x Strenght runeword Claws

Its gonna be 25% + 25% of crushing blow? Or just works 1x claw ?
