Personally I wouldn't drop the four set bonus for the items you've mentioned but I would for the blue aspect helm, frost adroit handguards, and chestguard of the recluse. At a quick glance at a recent wws it looks like the four set bonus procs about an average of eight times in a three minute fight. Not a tremendous amount of rage saved but slightly helpful none the less, sort of like unbridled wrath, not much of a dps incease.
