If you can gather extra thorium before going to Outlands, the best items to stockpile for and use to wow power leveling up initially, as they are saleable, will be the Imperial Plate Armors, Elemental Sharpening Stones, Darkrune Armors, Ironvine Armors, and Enchanted Thorium Blades. These can take you as high as 325.

The uncommon Fel Iron Chain and Plate sets and Fel iron weapons can then also help get wow power leveling to you to 325, although their saleability is iffy. At 325 make Lesser Rune of Warding until they go grey at 335. If you can get the primals, you can make the rare Adamantite Plate Bracers and Gloves, as they should be saleable, and your specialty rare breasplate or 1H & 2H weapons. Otherwise make Fel Iron Breastplates to 340.

At 340 get the plan for Lesser Ward of Shielding and make it to 350, when it goes grey. At 350 (and Honored with Cenarian Expedition) you can make Adamantite Whetstones, Sharpening Stones, and Rods to 360, also your skill 350 specialty BoP epic weapons or armor to get the last point or two to 360.

At 360 you can now make Eternium Rods to 375, learned orange at 360, yellow at 365, green at 370, gray at 375. Allow for 3-5 failures to get skillups.When WotLK releases there will be a number of cheap Cobalt plans to make wow power leveling to your character .
