I haven't played 60's myself since vanilla so i'm not sure what's the best gear setup/enchants , but this warrior from my server is pretty much BiS so he told me ,
He's prot specced atm , with arms gear i know but it gives you an idea of the gear , and that gear is better than the 'TBC' gear with Gem sockets in them.
Scum looks like your best bet for an Arms setup; however, Protection is my specialty. I have nearly every "BiS" item in my opinion and i've come to enjoy this setup, the only things i'm missing are Thunderfury and my Tier 2 Wrists. As for trinkets I remember that Styleen's Scarab was BiS however with the new changes to defense stats that came in Cata, i'm not sure if it qualifies it anymore.

This is my warrior setup, max strength, was better w/ titans grip fury but, its still really good even now. I basically 1 shot people and keep myself alive in a crowd w/ fast victory rushes. I also have a full aq set, bwl and mc set but this is what hits the hardest. Zêrø @ Blackhand - Game - World of Warcraft
