Alrighty... here goes:
You have the Patient title and yet no tier-9 gear? What did you spend all those Triumph badgers on? Go talk to
this dude. Tier-9 is generally considered baseline gearing right now and is a logical first-step after dinging.
At the time when I am looking at your profile you have some cheap level 78 crafted PvP gear on and several PvP-oriented talents which isn't helping your DPS. Remember that Resilience is a PvP stat and is entirely useless to you in dungeons. Look for gear with Strength as it's primary stat and a mix of Hit, Crit, Armor Penetration as other stats. Gem for Strength until you start to really understand your class better (read up on Elitist Jerks, here, and WoWhead).
As far as talents, compare what you have to
something more common for PvE.
If I had a fresh 80 warrior right now, I'd be running regular ToC for the upgrades but mainly for
the trinket. After getting everything I could out of there (should take a bunch of runs probably), start queuing for the ICC-5s.
Another trinket and
the axe are your main objectives, but there are other nice upgrades from there.
Now, the above are the easy things. There are certain things which are a bit trickier but really separate the scrubs from the good players (list adjusted for warriors).
1. If you queue as DPS, ONLY roll on DPS gear for your spec. Not tank gear, not "because I'm poor". Just roll on spec-appropriate gear for the role you are playing in the group.
2. DPS as much as threat allows. Download Omen and never, ever, never, ever, ever push past the tanks' threat. Yes, even if the tank is utter terribad. Don't *****, just stop attacking if you must and learn to deal with a threat cap. If you get tired of people not giving you enough room to ZOMG DEEPS, strap on a shield my friend and start clicking on Tank to queue. You'll learn why this is a rule right fast.
3. Stay on target. Always follow the tanks threat target which is often the one they're hitting. Good tanks will mark a skull for you to follow as the priority target. But NEVER just go bashing on something that the tank hasn't hit yet. I use a focus/assist macro ("/target @focustarget") to follow the tank but that's not always ideal. You just have to learn by doing. Also see #2 above.
4. Research is not asking /trade. If you want to know if something is an upgrade, if this talent is smarter than that talent or anything about your class; take the five minutes and look it up on one of the better sites aforementioned. Asking in trade chat is silly and will most often give you inaccurate, glib, or otherwise useless garbage. Learning where to find the info yourself makes you a massively better player.
5. If I use my mouse to turn, how do I click Rend? So wise, so true, so funny. If you don't already, learn to use your mouse to turn and use keybinds for abilities. I'm not even going to debate this with people.
6. It's called group utility for a reason. Warriors don't bring a ton of group utility but that doesn't mean you should let your shouts drop, ignore interrupts, or let the healers get eaten. Battle/Commanding shouts are nice buffs and if they're not being overwritten by another players buff, you should keep them up (be sure all melee AND the tank are in range). If you see a spellcast that is going off, stop it if you can. There's no reason why you shouldn't interrupt unless otherwise told not to by more experienced players. And if you see a mob get loose and start after the healer, a quick Charge to stun it can really save their butts. Whatever that little extra you can do to help the group succeed, is good.
Sorry for the wall of text but hope that helps. Good luck and welcome to the Wonderful World of Warrioroninging, part two: The Click-Rending of Cocoâ„¢.
