Somewhat independent of the particular fight transitions, you should know how long the specific fight will be. How many times should you be able to use Rapid Fire? When will bloodlust/heroism kick in? For on-use trinkets, how and when will you use them? Will you be using a DPS potion or a health potion on the fight?
Generally, you want to stack your "power up" buffs. Use your trinkets as often as possible, but do use them during rapid fire. For proc events, monitor them. They'll usually pop pretty soon into a fight, when they do pop your manual power ups to multiply the benefit.
This doesn't happen much in Cataclysm, but it used to sometimes be prudent to not blow everything at once. There were some level 80 boss encounters where you might blow everything and then find yourself incapacitated for a substantial amount of time. In those types of fights, spreading out some of the risk was more prudent.
