Generally the easiest way for a beginner to price an item is to look for other items at around the same level.

Let us say you want to get rid of some level 25 cloth boots - you could search the AH for cloth boots of levels 21-29 to see what the price range looks like then consider if your item is better or worse than what you see there and price accordingly.

"Better" means more desirable for the class that that item will attract. e.g. Rogues/Hunters want Agi on their items, so a "...of the monkey" with Agi/Sta is far more desirable to a Rogue/Hunter than a "...of the whale" with Spi/Sta.

Some green stuff is almost worthless like the "... of the whale" mentioned earlier, so you would be better disenchanting them or vendoring them, rather than wait for a clueless player to buy it (if ever). Green stuff tends not to vary much in price. Blues and purples have a much wider price range. I regularly buy blues priced below what I think it it sell for and grab them immediately, either to disenchant or resell.

Every server is different so allahkazam, wowhead, and thottbot can only serve as a rough guide to how much an item is worth.
