You may have figured this out by now, but I've been looking into getting high max res on a labs char these past couple of days so thought I'd chip in. Full disclosure, I have no experience with this fight - I am just theorycrafting.
Obviously you have +6/7 from Sleep:Laz, Kabraxis and Azmodan already.
Hide of the Basilisk SSU gives +4 light, but you may want to use Natasha's in this slot anyway (-2 to +5), or just get Tyrael's Might - I hear they're really common...
Witchhunters Helm is 2% max res all as you probably know. However, x4 light Barb Helm gives +6 max light and +10 absorb and a huge Vitality bonus as well.
Dementia belt SSU gives another +1 all if you happen to have one.
Adrenaline rush x2 and Death Ward can combine for another +3 (+4-5 if you can lotto the amulet).
So put simply: Charms @ 6 (min) + easy(ish) 3 on jewelry + easy 6 in helm = 15 + 75base = 90 max. To be honest, I'd go Natasha's if you can and get +3 (hopefully) max res on that (plus all the other juicy mods) and free up your jewlery - might be cheaper. But there are some other options too as you can see.
I, for one, would be interested in how you get on as I'd love to be able to kill Sam myself next season using a 2h barb
ps. forgot you had a Zan Esu - just makes this even more flexible for you.
