Bracers of the green fort are good if you cant get the ones off huntsman in kara.
All of the felsteel set is good until you can get replacments.
The epic helm Saltward Defender and the Iron tower gloves are probably not worth all the mats and money. Stick with the felsteel peices till you get kara epics or T4 gear.
Gryo- Balanced Khorium Destroyer (gun) is a good craftable for tanks worth having, imo.
The Red Havoc boots i belive you must be a BS with the plans to make and wear them, because i belive there bop when made. And so is the blue chest for sure its bop i know i made it for myself back in the day. I would definatly check some of these items you listed to make sure they are not Bop when made, save yourself some headache when you go to have them made.
I never knew about the cloak of eternity but it looks nice with low mats, but the Devilshark cape for tanking is better from last boss in Steamvaults,imo.
Really the best gear for tanking to be doing well in gruul or later comes from running kara, so my advice get in there.
There is something so appealing about backhanding someone across the face with a shield.
