Exactly what I do when leveling a new character, buy the 66 mods from the GTN, and gear yourself out. If you know your class and spec, you won't have any issues beating the enrage timers with that gear. Then continue to progressively gear your character.
Partisan gear or buy the 66 mods from GTN is really easy 55 HM's.
Buying the 66 armoring/mods/enhancements is much quicker than grinding out the old BH Coms for gear, and much more effective. Then use the BH Coms you get from running the dailies to gear your Companions.
