Damage is number one, but survivability (in this character's case hit points) are a close second. I wouldn't want to dip oracle, it just wouldn't make sense for the character (surprise! I'm a power gamer who also cares about character concepts). I wouldn't opposed to a sorcerer level and some DD levels. Would that be bad?

Were it not for your tiny CHA score, I would have suggested a two level dip as a metal mystery Oracle to gain the ability to cast Lead Blades and increase your weapon size yet another step.
can only have one effect that increases size... oh god this is the corner case twist the rules deliberately misinterpreted wording and take stuff out of context area of expertise. So yeah size increasing "antics" might fly since lead blades doesn't "actually"increase weapon size. Won't stack with impact though.

I'm still pretty new to gaming in general, so rather than judge you could always just help instead. Be that as it may, I just thought of a great way to manipulate my GM some more to alter DD a bit (blood of the dragons progresses barbarian stuff rather than bloodline abilities). I think I might make this a lot less mundane...

Titan Mauler does not remove the limitations for wielding oversized weapons, only the penalties.
Therefore, a Large Titan Mauler cannot ever wield a two-handed Huge, Gargantuan, or Colossal weapon.
A Large Titan Mauler can wield a one-handed Huge weapon as a two-handed weapon (and a light Huge weapon as a one-handed weapon.
A Large Titan Mauler can wield a light Gargantuan weapon as a two-handed weapon.
What a Large Titan Mauler is looking for is either a Gargantuan Aklys to be wielded as two-handed weapon of 4d6 damage, or a Huge bastard sword/dwarven waraxe to be wielded as two-handed weapon of 3d8 damage. Both options require Exotic proficiency.

Survivability is also gained not by overpowering the opponent but layers upon layers of effects and abilities to save you.
Do you ave cover? Concealment? DR? Miss chance? Temporary hit points?
Pick up a cloak of displacement lesser, to gain a 20% miss chance. It'll help mitigate attacks on you.
Pickup juggernaut pauldrons to get a cumulative attack increase as well as some dr.
Stoneskin gives a small dr buff, but also absorbs damage.
False life or another boosters give temporary hit points.
Fortification on your armor will help decrease likelihood of a crit or sneak attack damage.
Edit: sunder and spell sunder for barbarians are very powerful. Have fun.
