Slightly optimized Dinosaur-raging totemist build

[Eldhrimer]

Hi lads.
I've been working on this character for the past few days, and thought about sharing it with you, to get some feedback.
Just want to add that I rolled ridiculously well my stats. 18 16 14 18 18 12. The face of my DM was priceless as I rolled them before him. We're starting at lvl 6, but I've planned ahead the build.

Saurian Shifter (Traits: Longtooth, Razorclaw)
Str 18
Dex 18
Con 20
Int 14
Wis 14
Cha 10
Barbarian (lion spiritual totem, and wolf totem) 2 / Totemist 3 / Totem Rager 5 / Warshaper 5 / Weretouched Master 5 (bear) [pre-errata]

Flaws: Implacable and Bravado [Dragon Magazine #328]
Traits: Actually I don't know, I would like some suggestions
Feats:
1:Cobalt Rage
F:Longtooth elite
F:Shape Souldmeld (thunderstep boots)
3:Shifter Multiattack [stripped from BAB prerrequisites]
6:Extra shifter trait (beasthide)
9:Shifter Savagery
12:Open lesser chakra (shoulders)
15:Extra Rage
Extra (weretouched):Beasthide Elite
Extra (weretouched):Great Rend
18:Open lesser chakra (arms) [or open great chakra(waist) I don't know yet]

What I wanted to do with this character was to give him a more natural power growth, with some nice fluff, all my totems are renamed as Deinonychus, and I get the Deinonychus look with bear stats at the capstone of Weretouched Master. I have grown a bit fond of optimizing my characters, and that have cause me to me called by my friends "game breaker", I've tried to limit myself in this one. But given I enjoy optimizing, I couldn't help myself better than this. I wanted it to be real feral and ferocious when he goes into change and rage, but remain useful outside of it.
Ah, one last note. Open X Chakra and Shape Souldmeld are interpreted in the more wider sense. They give one additional bind and shape, respectively.

So, watcha think?

I'd try to get great rend earlier. Are you whirling Frenzy or normal rage?

Normal Rage.
I choose great rend just for the extra shifter change mostly. Not particulary impress with any of the other feats.
In wich level you would put it?

I would swap out the third level of totemist for fighter. The magical beast bonus save isn't all that important when you could pick up a feat. Even if it's just a fighter feat. Martial study, maybe? No screw that: Knockdown!!!!!!!!!!!!!!!

Knockdown makes your build monstrous. From Sword and Fist or Deities and demigods: Prereq = +2 BAB, improved trip, str 15. When you hit your opponent for 10 or more damage you get a free trip attempt against your opponent. Which synergizes pretty darn well with improved trip.

Maybe level 9 is where the damage boost from rend, plus the girallon arms, will help. Per set of claws, you deal an extra 5 damage on average. That's 10 damage if both go off. Shifter savagery increases die size two steps which is roughly an average of a +2 damage per natural attack per round. Assuming girallon arms again, you average a +10 damage...but DR will bone you a bit. Plus, with knockdown, you are more likely to trigger off of a rend which is damage tied to your second claw attack.

With totem rage, you can bunch essentia into totem avatar soulmeld to get the +2 per natural attack that shifter savagery promises anyway.
