I really like a mod called "auctioneer", it is a tracking program that helps you make smart economic choices. Once it's installed, you can "scan" the auction house periodically to update the mod's database on your machine, and it will create a baseline of what things are worth on your server. It will then suggest prices for auctioning things, tell you if it's better to vendor, disenchant or auction something, even scan the AH for undervalued items if you like. It's almost essential for making lots of gold in WoW if you're a fairly casual player like myself.
