Are there any Barbarian archetypes that replace rage?
Are there any Rogue archetypes that replace sneak attack?
Other then one monk archetype, are there any other ones that grant the Shifter caws?
Is there a reason you can't look yourself? Check all Barbarian archetypes that list rage here to see if any replace and not just alter rage. Dito for Rogue Archetypes. The search function can answer the third question (although I'd search for "shifter +claws").

There's a warpriest archetype which gets shifter claws, feral something.
Why do you ask? Any one of those might be for a character, but all three?
