Jagged Hornet Bracers (496) - Binds when Equipped, Heart of Fear trash
Bladed Smoke Bracers (463) - Sha of Violence, Shado-Pan Monastery
Groundshaker Bracers (463) - Xin the Weaponmaster, Mogu'shan Palace
Dreadful Gladiator's Wristguards of Alacrity (458) - 1250 Honor Points
Dreadful Gladiator's Wristguards of Accuracy (458) - 1250 Honor Points
Entombed Traitor's Wristguards (458) - 1250 Justice Points
Contender's Dragonscale Bracers (450) - Leatherworking
If you have the funds to purchase Jagged Hornet Bracers, they are nearly as good as the best bracers that drop in raids, so pick them up. If you're really lucky, you might be able to find the heroic Jagged Hornet Bracers on the Black Market AH, but don't count on it. If you aren't able to do that, the two heroic drops are similar, and the two Honor pieces and one Justice Points piece are a small step below them.
Raven Lord's Gloves (496) - Leatherworking
Gloves of Earthen Harmony (476) - Leatherworking
Dreadful Gladiator's Linked Gauntlets (464) - 1650 Honor Points
Archer's Precision Grips (463) - Commander Vo'jak, Siege of Niuzao Temple
Hopecrusher Gauntlets (463) - Sha of Doubt, Temple of the Jade Serpent
Brushcutter's Gloves (450) - 1650 Justice Points
Contender's Dragonscale Gloves (450) - Leatherworking
Raven Lord's Gloves are a raid-level craftable that will prove to be very expensive for quite some time after launch, as Blood Spirit comes from disenchanting normal and heroic raid gear. Gloves of Earthen Harmony are much more reasonable and are a much better item than the PvP ones, but the PvP gloves are among the strongest PvP pieces, and one of the two cheapest that will allow you to pick up the two piece set bonus. Since the bonus is strong, you'll want to pick it up until you can get some tier 14 gear from raids, but it's up to you if you want to go the cheaper-but-effective route and use the PvP gloves, or go the more-expensive but slightly better route and get your PvP 2-piece in some other way while picking up Earthen Harmony. If Raven Lord's are available to you, though, that answers that question for you.
Dreadful Gladiator's Links of Cruelty (464) - 1650 Honor Points
Dreadful Gladiator's Links of Accuracy (464) - 1650 Honor Points
Bindburner Belt (463) - Flameweaver Koegler, Scarlet Halls
Impaler's Girdle (463) - Striker Ga'dok, Gate of the Setting Sun
Contender's Dragonscale Belt (450) - Leatherworking
As with necks, cloaks, bracers and rings, the dungeon drops are slightly better than the honor pieces.
Legguards of Sleeting Arrows (476) - World Drop, Binds when Equipped
Legguards of the Crimson Magus (463) - Thalnos the Soulrender, Scarlet Monastery
Hopping Mad Leggings (463) - Hoptallus, Stormstout Brewery
Dreadful Gladiator's Linked Leggings (458) - 2250 Honor Points
Leggings of Twisted Vines (458) - 2250 Justice Points
Contender's Dragonscale Leggings (450) - Leatherworking
Legguards of Sleeting Arrows are a world drop and are your best pre-raid option, just remember to leave room for your PvP two-piece bonus.
Treads of Ardent Antagonism (476) - Sha of Anger
Bone Golem Boots (463) - Rattlegore, Scholomance
Treads of Fixation (463) - Raigonn, Gate of the Setting Sun
Dreadful Gladiator's Sabatons of Cruelty (458) - 1650 Honor Points
Dreadful Gladiator's Sabatons of Alacrity (458) - 1650 Honor Points
Contender's Dragonscale Boots (450) - Leatherworking
PvP boots have no PvE relevant socket bonus, so the dungeon boots should be slightly better. While Sha of Anger is technically a raid boss, he is easy enough to kill with any pug, even at a level below 90, that finding a group to get the quest for these boots should be easy. They are likely pre-raid best in slot, but they aren't a lot better than the two heroic dungeon options due to the lack of a socket.
Seal of the Windreaver (489) - Quest reward, Exalted with the Klaxxi
Seal of Hateful Meditation (463) - Taran Zhu, Shado-Pan Monastery
Signet of Dancing Jade (463) - Liu Flameheart, Temple of the Jade Serpent
Pulled Grenade Pin (463) - Saboteur Kip'tilak, Gate of the Setting Sun
Dreadful Gladiator's Ring of Accuracy (458) - 1250 Honor Points
Dreadful Gladiator's Ring of Cruelty (458) - 1250 Honor Points
Mark of the Dancing Crane (458) - 1250 Justice Points, Shado-Pan Honored
Roguestone Shadowband (450) - Jewelcrafting
The best ring available pre-raid is the quest reward for reaching exalted with The Klaxxi. If you don't have the time for that, any two of the 2 PvP options, JP option, or 3 heroic dungeon options are acceptable, the dungeon drops obviously being slightly better.
Relic of Xuen (476) - Inscription
Flashing Steel Talisman (463) - High Inquisitor Whitemane, Scarlet Monastery
Windswept Pages (463 - Lorewalker Stonestep, Temple of the Jade Serpent
Searing Words (463) - Darkmaster Gandling, Scholomance
Ghost Iron Dragonling (450) - Engineering
The Relic of Xuen is the new Darkmoon Card for Agility specs. Having both an Agility static bonus and an Agility proc, its value is much higher than its item level. This trinket may even be best in slot for heroic raiding. If you have the ability to do so, get your hands on one of these. The rest of the trinkets listed here are pretty strong, so use whichever comes easiest to you, but shy away from Flashing Steel Talisman if you're an Engineer. Flashing Steel is probably the best for non Engineers, though, as using it on cooldown causes it to line up with every Ascendance use. If you have Coren's Chromium Coaster, don't use it over any of the above options. It's terrible, roughly on the level of Cataclysm trinkets, and you're better off with a Ghost Iron Dragonling.
