Yes, 75 on d2 stats on Hell. Minion accuracy depends - for farming you don't need THAT much but for bosses having more is much better. So I prefer having a decent amount. I have like 10 Thur runes in my gear, which is probably a bit overkill but it helps. Having like 20k+ minion attack rating should be fine, I got 24k - 49k depending on the spirit on my lvl 129 Barb.
A tainted chest with +2 all skills gives more minion damage and attack rating, but the set might still be better since it gives +1 minion and STR%, idk - both are good. If you got the set I wouldn't bother crafting the chest I think.
