Depending on how much money you have willing to spend. As other said contenders work to start out, just dont pay much they are ilvl440 which is crap. Greyshadow Chestguard (Ilvl 476 epic) and Greyshadow Handwraps or w/e are ussually cheap (Server dependent) as they mats are easily farmed/obtained, kinda depends on the price of spirits the crafter charges, (On my server it ranges from 300~800 per), both Chest and hands take 8, so pre mats your looking at anywhere from 2400g~6k. You MAY want to look into the 496 as Blood Spirits are dropping in price rather fast, as it seems there might be some duping trick RMT found (lvl 1 characters selling 31+) these pieces wont be upgraded as fast as 476 but cost much more.
As for stats I can only speak on monk but Haste is stupidly weighted for dps monks you want to pretty much get haste up til around 5 or 6k (less if you noticing your energy capping from to high of energy regen) then crit, mastery is terrible kinda, and the more mastery you have the less haste you need because mastery procs make tiger punch/blakoutkick proc free. So you need to balance haste mastery really weird and since its RNG procs its a pain, so most spreadsheets go Hit>Agi>Exp>Haste>Crit>Mastery.
If you have archeology, I lvled my monk with an upgraded Spear of Xuen (Which is OP its a 463 and can be upgraded to a 471 and equipped at 85). I kept that on til I was stupid lucky and got a Sha touched agi staff to drop off LFR(without tokens, yet my rogue who has his legendary gem waiting for 4 weeks now, has wasted 10 tokens +6kills trying to get the Sha touched dagger, I've gotten 2 teir tokens, 3 trinkets(which are ranked worst then heroic trinkets), and 2 belts. Oh and all of those items are useless since I already had better in those spots)
Currently dual-wield is more Dps then 2handed by a small margin, but 1handed agi weapons hate me and I never see em drop, and I believe this is more of the effect of being able to get dancing steel x2 vs alone on a 2hander.
Just want to point out one thing about reps, dont level anymore toons til you get the revered rep tokens with atleast Klaxxi, Shado-pan, and Tillers. I was silly and leveled my rogue week 1, then my Warrior by week 3 or 4 of expansion, then 5.1 came out and introduced the tokens. Now on Dracian I grinded dailies til exalted with all for mounts/etc to see all the stories, bacon did as little as possible to get lesser charms every week. I leveled my Monk and Dk next after 5.1 and they BOTH are way afarther in reps all reps then Bacon who had almost a month and a half head start. Hell, I exalted Klaxxi on monk, and War is still at lik 12k revered, and that was doing a week ish of only Klaxxi dailies on monk.
With the Revered tokens all rep gains are increased 100% across all toons forever. I was able to barely be revered after doing townlong steppes + 1 quest turn in of sha of anger claw with Shado-pan, and I was 8k ish into revered just doing Klaxxi rep while leveling 89-90. Tillers I was revered after opening quests (did while in Four winds@ 86) and 1 day of dailies at 90, you can hit exalted and have a fully unlocked farm after 4 days if you time it right, or 5 days. Those sets of dailies take approx 10 mins, maybe a tad longer if you do em at a busy time.
Anyway hope this helped.
