There is this relatively cheap ring to ignore staggered for 5 rounds per day.
Having pounce will let you full attack despite being staggered if there is a foe at least 10 ft away but no more than one move action's distance from you.
The Restoration subdomain of Healing domain can cure staggered.
A level 6+ Paladin can get a Mercy to apply to his lay on hands to heal staggered.
