Oh - and rage clickies:

ML1 - Ring of Rage 1:30, 1 charge
ML2 - Brawn's Spirits 1:30, 3 charges
ML3 - Barbarian's Spirit 1:30, 1 charge
ML6 - Armor of the Amok 1:30, 3 charges
ML7 - Bloodrage Symbiont 1:30, 3 charges
ML8 - Blood Machete 1:30, 1 charge
ML20 - Epic Brawn's Spirits 2:30, 5 charges

I would usually hit the clicky when first ramping up the rage because it lasts longer, but once you have barbarian rage active you can no longer activate clickies and can only sustain with rage pots (30 second intervals) or the rage spell from a wizard.
