#1 priority for you would be to level THF to 15 and sub it to your lvl 30 WAR.
Then at your level the safest and most efficient place to farm is Taronghi Canyon near Windurst.
Bees = Beehives Chips
Pygmaoi = Sarutu Cotton
Saplings = Seeds (and if you think seeds aren't worth much, check the AH for stacks of 12)
Dhalmels = Dhalmel Hides and Giant Femurs
Crawlers = Silk Thread
Elementals = Specifically Air Elements
You can also "Steal" the cotton from Pygmaoi and Silver Beastcoins from Yagudo Persecutors and Pipers quite easily with your THF sub. The key here is to get your THF sub to 15 for Treasurehunter. Without a THF subbed, farming can become very tedious and non-productive.
