smashey barbarian help

[Cornielius]

I'm working on a build for a barbarian- a happy type, who likes smashing things and running around the battlefield.

Here's what I've got::

Dwarf Barbarian
STR: 18 (17 pts)
DEX: 13 (3 pts)
CON: 14 +2 racial (5 pts)
INT: 10 (0 pts)
WIS: 8 +2 racial (-2 pts)
CHA: 12 -2 racial (2 pts)

Traits: ?, ?
Level 1 (barbarian 1): feat (power attack)
Level 2 (fighter 1): feat (furious focus)
Level 3 (barbarian 2): feat (raging vitality), rage power (smasher)
Level 4 (fighter 2): feat (steel soul), +1 dex
Level 5 (barbarian 3): feat (improved sunder)
Level 6 (barbarian 4): rage power (swift foot)
Level 7 (fighter 3): feat (greater sunder), feat (improved overrun)
Level 8 (barbarian 5): + 1 str
Level 9 (barbarian 6): feat (extra rage), rage power (strength surge)
Level 10 (barbarian 7):

Gear: furious greatsword- hopefully adamantine, rhino hide, the obvious belt, ring of sustenance, potions of?
Skills: Acrobatics, Perception, Survival, Intimidate or Knowledge (nature), some climb, some handle animal, some swim, some linguistics

I haven't done a barbarian build since playtest and have been playing druid and cleric, so I'd welcome reviews and advise.
I'd prefer no stats less than 10, but I'll listen to your thoughts for race, class levels, archetype, traits, feats, and whatever else you want to mention.

Seems kind of hard to smash things with a slashing weapon. This Rage power would fit once you hit Barb 6 and would mesh well with this racial alternate, though your choices all still fit. Getting a Lucerne hammer or a Bec de Corbin would help sunder some other things, too. (Plus some reach!) If you still want to threaten close, too, consider wearing a Dwarven Boulder Helmet.

I don't recall Steel Soul being a combat feat, so you can't get it at level 4.

[Cornielius]

Thanks for the catch on the Steel Soul feat, I'll switch it around.

For the ground breaker rage power and the dwarf trait to ignore difficult terrain caused by it, I saw the combo, but would probably fail to take advantage of the terrain effect correctly.
I tend to reduce in-combat thinking to 'get em' and flanking.

The great sword is a remainder from when I was thinking 1/2 orc for race. For dwarf, I'd probably go with earth breaker and the racial archetype that favors hammers.
The dwarven long hammer and boulder helmet combo is an idea, too.

Any other suggestions from those more familiar with barbarian?

[Skizm]

Breaker archetype for half your level as damage to sunder and Battle Scavenger at level three for using improvised and broken weapons without penalty.

Do you need smasher power if you're using an adamantine weapon?
