Mote of Earth:
(Blade's Edge Mountains) Sundered Rumbler - (Basically above and all below Area 52) - 18.8 - http://www.wowhead.com/?npc=18881

Mote of Mana:
(Netherstorm) Mana Wraith - 36.60 and 31.73 (Anywhere above Area 52 and more below. While you're at it, kill the Nether Rays as well, they have just as good of a chance to drop and are mostly in the same area) - 25.8 - http://www.wowhead.com/?npc=18864

Mote of Life:
(Zangarmarsh) I didn't find any specific place to farm for these because the zone is just rich with them. But I would suggest farming the Bogg/ Starving Bogg Lords and Fungal /Starving Fungal Giants because they are all very close. - The Spawning Glen (SW Zangarmarsh) and East of there is the Quagg Ridge - Very similar drop rates on all 4 mobs that I pointed out, 18.2 to 18.8 - http://www.wowhead.com/?item=22575#00Rmz

Mote of Shadow:
By far the most commonly found mote. This is dropped in almost every zone and can be easily farmed anywhere. But there may be a few exceptional areas just because npcs that drop them are close together, non-elite, and easy to kill. Here's one spot in a few that are exceptional:
(Nagrand) Voidspawn - Again, no specific coords, but all around Oshu'Gun, the bigass crystal SW Nagrand. - 18.4 - http://www.wowhead.com/?npc=17981

For Rugged Leather

Go to Razorthorn Shelf in Outland. The little guys give you one or two every time.

For Fel Iron

Hellfire Pennisula is great. Do laps around the zone, hugging the mountains. There's a lot.

This is made a lot easier at 4:30am, as there are no farmers.

Adamentite incoming soon.

Get Gatherer if you haven't already. Helps a ton.
