As of Patch 3.1 of World of Warcraft, there are no longer any "daily" quests in Wintergrasp. They've been moved to being "weekly" quests.
There's a lot of information about the quests in Wintergrasp, including the random weekly quest players will want to hunt down. See the link to WoWWiki's page on Wintergrasp Quests to get the full deal.
Probably do daily quests or heroic instances :)
Badges of justice are found in heroic content and raids in The Burning Crusade expansion. Badges are are also a very rare reward for one of the Shattered Sun Offensive daily quests.
Daily quests are quests that you can only complete once a day, but normally have a fairly good reward. Examples of daily quests would be Reen's Daily Quests in Arcangrove. Daily quests are normally listed under a button called Daily Quests in an NPC's options.
Currently for most of the daily quests, it is 13g and some silver for each daily and regular 75-80ish quest. This will probably change in cataclysm. For lower level quests you still get gold but at a reduced amount, mainly because at 80 you no longer gain experience. Again, this might change in cataclysm.
You can grind Reputation Quests. I would suggest you to do Quests that you can do over and over again, instead of doing Daily Quests or Story Quests. :)
grizzly hills are located just to the right of icecrown in northrend. it is a very good place to level up around 73-74 after tundra. you can gear up fast and the xp is quite reasonable for the simplicity of the quests. for level 80's it is also a very good place for daily quests.
at worldofwarcraft.com you can have a 14 daily free trail
Tol Barad is the Cataclysm outdoor PVP zone and daily quest hub, kinda like Wintergrasp and Isle of Quel'Dalas mixed together. Whoever controls the prison (control is obtained by a battle every 2hrs or so) has access to dailies that have even better rewards than the other dailies on the island and is eligible to go into the instance that is located there.
Tuesday is broom of doom, Friday is magma axe, and Saturday is sludge blade
There are a few ways of obtaining this reputation: 1) Do the Deepholme quests The questline here will reward substantial reputation, and is a prerequisite to obtaining the rewards (including the tabard, see point 3). You should be able to hit Honored from these quests, mileage varying depending on whether your guild has the perk that increases rep gains. 2) Daily Quests Once you completed step 1, daily quests open up that allow you to gain a chunk of rep every day, and also award certain achievements if you complete certain quests 10 times. 3) Dungeon grinding Buy the Therazane tabard from the rep vendor at Therazane's Throne, and wear it while running (heroic) dungeons. Rep gained will then count towards the Therazane faction.
The Kirin Tor is the ruling faction in the magical city of Dalaran. They have several daily Cooking, Jewelcrafting, and Fishing quests. All classes start out as neutral with the Kirin Tor, except mages, who start out as friendly. There is a tabard available to champion them when you do level 80 heroic dungeons, gaining rep faster.
The Christmas like holiday that is in World of Warcraft is called the Feast of Winterveil. It goes from December 15 until January 2. This is an annual event with a daily for level 80-85's, presents on December 25, and achievements.
