all about the zone, familiarized yourself with the gameplay, and have some sort of idea on the strategies on how to win it, let's have a look at the daily quests associated with the zone. The cool thing about Wintergrasp dailies is that they are the only source of Stone Keeper's Shards outside of dungeon bosses and the only way to obtain them whether or not your faction controls Wintergrasp.
The Wintergrasp dailies are also an excellent source of Honor and some can be done without actually doing any PvP whatsoever, which is a strange new trend in Wrath of the Lich King, where the PvP side of the game is accessible entirely through PvE. The very first daily quest is self-explanatory -- Victory in Wintergrasp, which requires players to win a battle for the zone. Alliance players get this quest from the Tactical Officer Abrahmis, while Horde players get it from Tactical Officer Kilrath. If you control the zone, these NPCs can be found in front of Wintergrasp Keep, where the Titan Relic is housed. If you don't, they can be found in the landing camps on the East or West.
The quest seems to be currently unavailable in the game, as it has been very buggy and many players have reported not completing the quest even after a victory and having the requisite Rank. I'm certain the quest will return in bug-free form with Patch 3.0.8, if not hotfixed sooner. Completing the quest awards one Stone Keeper's Shard, 13 Gold 23 Silver, and 1241 Honor at Level 80.
