my advice to you would be to get the badge legs/belt([item]Girdle of the fearless[/item][item]sunguard legplates[/item]) and get 3 epic stam gems from the vendor and stick them in.
also pick up the [item]brooch of deftness[/item],[item]Slikk's Cloak of Placation[/item] and maybe even the [item]warbringer shoulderguards[/item].
the badge ring certainly would not go astray but for the life of me i cant remember its name! (haha)
awesome guild name btw!
and as for the "am i ready" thing, can i point you in the direction of Vene's tanking blog, specifically this post: Am I ready for this instance? - Warriors - TankingTips.com
