What are you currently working on in game?
Personally, gemming agi/dodge and reforging mastery has been less desirable for me. You can never have enough rage
Rage means higher up time on SD (which works out to be more dodge that gemming dodge) and more healing for FR. Right now because of the amount of rating that is required to get 1% dodge or 1% damage reduction from mastery just doesn't compare to getting more stats that give you rage per second.
Take a look at the
Stat Weights and
SD vs FR posts I've made and take a look at the math behind all that.
