It'd be much easier if you'd post the Shadow Lair you're going to do, but I assume that it's Snarby judging by set you want to craft. You need 2 pieces of Nightmare Mane to craft full set, you'll get 1 obviously from your run so I advise you to buy 2nd one from someone who's in your party or from Auction House before the run.

About the gear, Vog set won't help you much beside ASI bonus, much more viable option would be Skolver, you'll struggle against all undead monsters there but you'd get the edge during boss fight which can cause troubles. But if you'll be very careful you can stick with your Vog, smaller cost. From your 2 shields better option is Crest of Almire, more common options are Barbarous Thorn, Dread Skelly shields, but you can save CE by going with CoA.

For weapons, you'd be really happy with piercing sword, Final Flourish is the most common option and recipes are in Hall of Heroes. From what you have/you're close to have, both Glacius and Argent Peacemaker are viable choices, if you have 2 slots you should pick a piercing sword and Argent Peacemaker as 2nd (3rd: Glacius/Divine Avenger, 4th: Polaris/Shivermist Buster).
