[pf] What's some good feats for 8th lvl barb?

[Firia]

I'm just looking for some good suggestions for a lvl 8 half-orc barb (that is, lvl1 ranger/lvl8 barb, for a lvl9 character) in terms of a feat. I've mostly referenced the main book for Pathfinder, and I haven't been super impressed with my options. Just looking for some options outside the mainbook. Or maybe there's some prereqs I should be building up towards something great.

The character is a half-orc, with focuses in Strength, Con, and just enough Dex for the Dodge feat, and lacking in cha. A typical build, I assume. He just picked up some boots of Haste (10 rnds/day), is a nutso damage dealer with an adamantite +1 Frost 2H Great Axe. He's proficient with the 2H axe, and a tracker by trade with max ranks in stealth.

What feats do you already have? There's some feats that most 2-hander melee should be taking, like Power Attack, Lunge, Combat Reflexes and Furious Focus. Barbarians have some unique demands as well, like Raging Vitality, Extra Rage Power, and Raging Deathblow.

A good place to get feat ideas is a class handbook; they can also just be fun to read in and of themselves.
