Let's add the piercing quills to the tail attack. Frankly, I also fancy letting them attack with quills at melee, too, like the howler.
Agreed!
Its Inexorable Gnawing should choose one option from "victims opponents".
Good point.
We need to give it the Dire Beast SQ to explain the good Will save.
Better yet, let's just fix the Will save as appropriate for magical beasts.

I see no need for these to have good Will saves.
I'm tempted to remove the separate "Quills" attack from the melee line and incorporate it into its tail slap, e.g::
Attack: Bite +5 melee (1d6+2) or tail +5 melee (1d6+3 plus quills) or 4 quills +5 ranged (1d3)
Full Attack: Bite +5 melee (1d6+2) and tail +0 melee (1d6+3 plus quills) or 4 quills +5 ranged (1d3)
Quills (Ex): Melee combat with a quill is dangerous. An opponent who attacks a quill with a melee weapon that does not have reach must succeed on a DC 16 Reflex save or be struck by 1d4 quills. Each quill does 1d3 point of piercing damage (plus half the quill's Strength bonus, if any) and lodges in the opponent's flesh, imposing a -1 circumstance penalty to attacks, saves, and checks per quill (maximum -4 penalty). Removing a quill inflicts 1d3 point of additional damage to the victim unless a DC 15 Heal check is made.
Furthermore, any opponent a quill hits with its tail attack will also be struck by its quills, with damage as above. If the opponent succeeds on the DC 16 Reflex save, it takes half damage and the quills do not lodge in its flesh. The save DCs are Constitution-based.
That'll do.
