Testament of Vanear if you don't have better already. +10 WIS item with some focus or another for your secondary slot. Might be soloable, but bring a friend anyway just in case.
Other than that, I don't know. Never played a druid past level five
Search the Qeynos Hills zone on this site for Bear Hide Armor. The quest NPC is near the Surefall Glade zone. The Bear Hide belt and cape aren't wonderful (just AC), but the boots have Extended Enhancement I which will at least help with your 20th and under buffs. Decent AC, too. I believe it requires 15 gold (not plat) and a medium quality bear pelt.
