So I have a 37 druid and I want to farm a full set of gear for a troll warrior.
 

What pieces do I need to farm for a Troll warrior to start out and last him to his 30's and 40's

5/55 rings, two cheap procing weapons (yak clubs sound about right) and a set of banded would get you started at a decent price.

Hero bracers will be easy too. Bracer of scavenging should be doable as well.

It takes AC and HP gear. Pretty straight and simple sort of like the Warrior class is. Lots of strength and stamina.

It's a longshot, but Haymaker the SM?

Crafted is very decent for the level and you're at a point on the main where you'd be able to complete the quests.

You probably want two weapon sets if you can do so - one to get you aggro, one to get you dps. The first is easily affordable as suggested above with yakesha proc weapons. The second is most easily and cheaply done via 2-handed weaponry.

Stack AC, hp and stamina. If you want to avoid pulling your hair out, consider either buying a jboot mq or camping the AC for your war... if you get caught in the open by something bigger than you, you'll have two options: beat it to death or run and hope for the best. Jboots increase the lifespan of your average warrior by several seconds by vastly improving the second option.
