At home in the shadows and skilled at disappearing from sight, the Rogues of Azeroth are most comfortable when acting in the background. Twisting events to their favor, striking only when advantage is greatest: this is where a Rogue excels. With their cunning tricks, physical abilities, and mastery of concealment and disguise, Rogues have no trouble finding employment as thieves, cutthroats, spies, and assassins.
Rogue's PvE Guide by Zealot
Rogues are a really valuable dps class on dungeons, heroic or not. As a rogue you will be able to peak sky-high DPS. In order to achieve that you must first know tha basic things and i am here to let you know some. As a rogue i prefer the Sword/Sword S&D + Rupture spec 20/41/-- [Slice'n'Dice + Rupture Spec]. While using this spec , Slice and Dice must be always up. Same goes for rupture. Personally i peaked 1.1k Personal DPS with this spec while fighting The Lurker Below. Also valuable is the Fist/Sword spec which provides you with 5% more critical chance but also gives the sword spec bonus, granting you one extra attack with your main hand , which is still affected by that 5% bonus crit. [Fist/Sword S&D+Rupture]
A rogue is also useful as a crowd control. You can use some of these useful on instances forms of croud control.
Vanish Pull
A vanish pull basicly means pulling a pack on NPCs with your ranged weapon then vanishing, granting you the chance to get both an opener at the pull and making the mobs easier to be tanked.
Evasion OT
"Oh no! Healer on fire!" As a rogue you can always pop evasion and offtank the mob that got into the healer,untill the tank reaches you and picks it up. Personally i use this alot on harder instances such as Heroic Magister Terrace, but it must not be used during a raid (chances are he will one shot you and the mob will go all out killing the raid).
Stunlock
Stunlock does not mean that the target is always stunned. It actually means "I kill you dont attack me!". Its really useful as a CC since you can take care of more than one mob ( [Sap] ) if CC is lacked. When stunlocking in an instance i follow this circle:
Cheap Shot > Sinister > Shiv > Rend > Kidney shot > Blind > Vanish > Start over again
Basicly by the time your kidney shot is over the other mob will be dead and the tank will pick the stunlocked mob.
Hit Rating
Hit rating is one of the most important PvE Stats for a rogue.When you have enough hit rating (around 320 cap) you wont miss a single shot, that means that you can no longer lose energy by moves that fail. The hit rating for starting Pve (heroics) is around 185. The hit rating for starting raiding (Karazhan) is 200. Expertise is also important , which can be easily capped by having 26/26. As a human rogue i cap expertise by having [Shard of Contempt] eguiped. I get +42 expertise plus +5 human racial plus +10 by talents , reducing the chance an NPC will dodge/parry my attacks by 6.50%.

LockPicking
I dont know whether this fits on this part but lock picking is a skill rogues usually ingore. Its really useful since you can open lockboxes or pick lock locked doors/chests that provide you with extra loot.When i was leveling my lock picking i got a blue drop form a lockbox and i sold it for 100g (Example).
Anyways using this guide i leveled my lock picking to 350/350 in 6 hours.
