Off the top of my head:
371 Pvp Helm
365 Molten front neck
371 Pvp Shoulder
365 Molten Front back (or 2 FL trash clears for 378 rep cloak)
378 VP Bracers (Haste/Spirit) or 353 Troll Bracers (if you get lucky)
359 Crafted belt (or 4 more trash runs of FL for 378 belt)
359 JP Spirit/Haste Boots (or 378 crafted Haste/Spirit boots)
359 JP ring
365 Molten Front ring (from Phase 2 vendor)
359 Volcano Card (from DMF)
365 Molten Front trinket (Moonwell Chalice)
either 359 Pvp Weapon, 353 Troll weapon or 378 BoE staff/Dagger
353 Troll Heroic wand (or buy the 378 VP Wand 1st week)
JP converts easily into Honor hence my inclusion of PvP gear. The 2p setup beats any combination of 359 and below helm/shoulder outside of T11.
Don't waste JP on Soul Casket at least not before getting all the other JP/Honor items - there are a few 346 trinkets that are better (Witching Hourglass, Gale of Shadows, even Sorrowsong.)
Soul Casket is indeed pretty bad before t12 4set bonus (where mastery gets very much better). I'm so used to those statweights that I totaly forgot that!
The PvP helm + shoulders is indeed very good considering they both sport haste, however, they will resoult in a very big lack of intellect and should not be used by anyone aiming on entering FL in my own opinion (hitcap geak). You can roll with them and screw hitcap though.
Some reforges are pretty out of the window to I think considering I used my own statweights (it's correctly gemmed though) and I can't bother to redo it
