Just got half a dozen new items - Advice

[Leviathan]

Hi all. I wasn't sure if this should have gone in the Armory thread or here. If it's in the wrong one, moderators please give it a boot

(Armory Link The World of Warcraft Armory) (Please ignore the Dodge/Defense gems. I overcalculated how much defense a couple of pieces would lose me. They'll be fine-tuned after the main decisions are made). Currently an Unholy tank.

Anyways. Last night I finally got my first full-clear of Naxx 25, and picked up half a dozen new items (I think my DKP has gone below absolute zero).
A couple of them were pretty strict upgrades:
T7->T7.5 shoulders
Minion Bracers-> Bracers of the Unholy Knight
Plague Impervious Boots->(Sabatons of Endurance - Item - World of Warcraft)
10 man Badge neck->Heritage.

However, the last two are giving me a bit of a problem trying to figure out what to do with:
T7.5 Pants token (Valorous Scourgeborne Legguards - Item - World of Warcraft).
(Cloak of the Shadowed Sun - Item - World of Warcraft)

I'm currently using:
(Dragon Brood Legguards - Item - World of Warcraft)
(Cloak of Peaceful Resolutions - Item - World of Warcraft)

The main issues that I'm having is wondering if the stam/avoidance increase is worth the hit rating loss (I'm on 6.5% at the moment), this is especially true for the legs, since it'd be a 1.5% hit loss, for a reasonable but not huge avoidance/stam increase.

The cloak is a little more complex. Do I just use the Shadowed Sun one, or do I get the 25 man badge cloak (Platinum Mesh Cloak - Item - World of Warcraft), which would mean no Hit rating loss.
However my other option for my badges (when I get 4 more) is (Kyzoc's Ground Stompers - Item - World of Warcraft), which would net me more avoidance than the Sabatons of Endurance, but would be a pretty hefty Expertise loss.

So. Thats my conundrum and I just dont know which way to leap and which combination yields the best results, and I'm currently at work so my calculation chances are a bit limited.

Does anyone have some advice/reccomendations for me?

I can tell you safely to get the emblem cloak. Hands down, it's the best cloak in the game. Since you already have the Sabatons of Endurance, I wouldn't bother getting the emblem boots. About the pants, they are so similar that I'd probably just use the Dragon Brood and turn the token in for a pair of DPS pants.
