So if my character has 2 claw attacks and a gore attack do I get to choose which is Primary? Are they all Primary? How do I assign the -5?

All are primary unless what gave you the weapons stated that they are secondary. the only time they would revert to secondary is if you attack with a weapon at the same time (like an unarmed attack are armor spikes).

this link to the pathfinder PRD shows natural attacks and their default damage, damage type and primary/secondary status.

So Abyssal Blood Line and Fiend Totem rage powers both operate at full attack bonus if I launch a Full Round Attack with my Barbarian?

Yep, full damage and to hit for all three attacks.

You can achieve a similar thing using a couple of the optional things for catfolk or the natural weapon ranger, too.

Natural attacks can be really good at a certain level range, but they eventually fall behind manufactured weapons in terms of versatility and potency.

Exactly.
If you play lower level games, and/or PFS (which is mostly lower levels, rarely reaching the limit of 12th) it works quite well.
Tengu is an allowed race right now in PFS and can start with the three attacks.
The fact that the bite is B, P, S can be nice vs. DRs.
Of course, if you are a Rogue, it triples the possibility of adding Sneak damage.
Also, the fact you add the STR bonus (not 1/2 for off hand etc.) is nice too.
Can be quite fun at lowish levels…
(you can also go Warpriest with Deities that have bite as Favored Weapons, and take Weapon Focus for your claws, which bumps your damage for both types of attacks and enables you to then make them Magic etc. at level 4 etc.)

In reply to swordchucks (msg # 5):

You can keep up if you keep picking up attacks, usually through items and all of them get buffed by your amulet. It's not hard to pick up 5-6 at full BAB, full damage and full enchantment, which should be competitive with full attacks with weapons.

For instance, a skinwalker ranger use his natural power to gain 2 hooves, and a gore. Pick up two claws with Aspect of the Beast at 2nd, Pelt of the Beast gains a bite attack. Fleshwarped Scorpion's Tail/Wyvern Cloak can add a tail attack. I'm sure there's more if I dig.

And of course, there is always the multiattack feat and using the natural weapons with a normal weapon attack. Make them with unarmed attacks and you still get the amulet bonuses and the natural attacks are only -2 attack.

So high level natural attack builds can be competitive, it just takes planning, cash and the ability to buy/have enchanted the items you need. If you're in a 'random drop' world and no one has craft magic feats, it's much harder.

Im in an Arena game with a Wild Rage barbarian who has Abyssal Blood and Lesser Fiend Totem. I plan to push those as far as they can go, though so far I have only found Amulet of Mighty Fists and Deliquescent Gloves to improve my natural attacks. I am going to keep looking, maybe find something with Giant Growth build in or something. Oh and take the Elemental Rage powers giving me 1d6 additional elemental dmg on all melee attacks. But that is 4 levels off.

I feel as though that character started off on a bad leg that will only get worse as he levels.
