Question of items/gems

[Kouryou]

I currently have two items, gloves and a belt and I recently recieved two items from the TotC and I am now not sure which to use. I'm currently using my tanking gear for heroic instance tanking (sadly not quite there for raiding yet) and for solo'ing the older instances. So would like items that are good all-rounders for keeping threat and keeping me alive longer ^^

Current items I have (with gems) are as follows:

Gloves - Fireproven Gauntlets (Enduring Eye of Zul)
Belt - Waistguard of the Risen Knight (Enduring Eye of Zul)

Items I have picked up (with gems):

Gloves - Mercy's Hold (Bold Cardinal Ruby, Enduring Eye of Zul)
Belt - Girdle of the Pallid Knight (Regal Dreadstone, Enduring Eye of Zul)

If you have any suggestions for which gems I should be using instead please let me know :)

Thanks for reading!

First get badge shield. Lichen guard wont work on keeping you alive vs lvl 80 mobs

Back to the gems

Early gemming for lvl 80 tank:
Red: Expertise/Sta
Yellow: Defense/Sta
Blue: Sta

Later gemming for lvl 80 tank:
Red: If expertise lower then 30 - read above, if not - dodge/sta
Yellow: If hit higher then 200 - read above if not - hit/sta
Blue: sta

Ignore the shield I was using that for solo'ing older stuff :) I use Royal Crest of Lordaeron normally. Thanks for the information about the gems but what about the items themselves?
