"I am currently leveling my first Horde character through Outland (Hellfire Peninsula right now). What quest hubs should I be on the lookout for lore-wise? I've heard Nagrand was good (being the home of the Orcs or something I believe), what else should I not miss?"
I haven't taken a Horde character through Outland yet, I've only read the quests and all of that on places like Wowwiki and Wowhead. I'm going to take a stab at this question anyway in the hope that our readers will have some thoughts on it as well for the comments.
My stab at this: Nagrand is very, very good, but you need to make sure you do pretty much every quest chain there. It opens up the truly epic questline after you've done almost everything else. Blade's Edge Mountains has a great quest chain involving Rexxar, and Shadowmoon Valley has amazing quests for both factions. I personally love Zangarmarsh because of its overall ambiance, but that's just me.
"Is there a website that approaches PvP like Elitist Jerks approaches PvE?"
"I'll admit I'm not the best PvPer, but I gotta say that rogue stunlocks seem ridiculous. I know it depends on which class you're playing but is there any good way to beat them? Are they considered OP? Even with my trinket it seems unfair that I go from full health to dead without a chance to fight back. Not looking for advice so much as what the overall opinion on this is. I'm guessing nothing but rogues laughing at me."
If you don't have good PvP gear (and I mean really good gear, I'm talking epics. Those blues don't cut it), Rogues will be one of the classes that destroy you, along with people like Death Knights and Mages and Ret Paladins. When you're in actually good gear, the playing field levels out quite a bit. Rogues can't pull off the super-gibs nearly as well anymore.
I've found that the key to breaking a Rogue's stun chain is to trinket the Kidney Shot. Just wait out the Cheap Shot, let it happen and run out. When the Kidney Shot lands, that's when you trinket. If you could tell us your class in the comments below, I bet people would have other tips for you as well.
"Argent Tournament Dailies - Why do I have both an Argent Lance and an Alliance Lance in my bag? Is it safe to get rid of one or both? I know there are lance racks around but are they for the alliance or argent lances?"
There are two different types of lances for flavor, but as far as I can tell they don't serve any different functions. You can do all of the quests with just one type of lance. You can throw one away. You can throw both away if you want, and just grab one off of any rack if you suddenly need one. It doesn't matter if it's an Alliance(or Horde) or an Argent lance. They both work.
