Another badge gear question

[Indolentpyro]

I've been a long time lurker here, but what I can gleam from advise given to others isn't specific enough for what I was wondering...

I currently have [item]Jade-Skull Breastplate[/item] and [item]Timewarden's Leggings[/item] that I am looking to replace with the new badge gear (once my server gets the vendor) I currently have 100 badges, so I can get the replacement for one right away.

To get to the point, my question is: would it be better to get [item]Chestplate of Stoicism[/item] first, or [item]Sunguard Legplates[/item]

my armory is here.

feel free to point out any other weak points in my gear as well.

(and a preemptive thanks for any and all advise)

(felt as it might be relevant to suggestions)
I am currently Kara weekly we usually down everything but netherspite and nightbane and we have started into ZA (got the first boss down a couple times).

Since you not downing Nightbane or Zul'jin yet, i'd buy the chest and get the legs from Curator.
