Finwe pointed out that if you are leveling a new Priest as an alt, and you have a level 80 main, you should pick up some Heirloom items if you have the Emblems to spare. If you are not familiar with the relatively new Heirloom Item system, here's the skinny. These items bind on account, meaning you can mail them from your main to your alt, as long as both toons are on the same server. The stats for the item change depending on the level of the toon carrying the item, and are usually approximately the same as a Rare item of the toon's level. You can enchant these items, but the enchant cannot have any level restrictions, or you will not gain any benefit from them.
Please note that if you need to convert your Emblems of Conquest to Valor and then to Heroism in order to purchase these items, I do not think you can do this at Brammold Deepmine - you will need to go to your factions' seller, and convert them via the other vendors nearby - it's a pain in the butt process too.
