I did my first Heroic the other night. Empire's Black Talon. It was a joke. I found it easier on heroic than I did on normal back at levels 10-15. Mainly because back then, I didn't have interrupts and now I do. I kill the captain because the robot boss is easier than the group of 4 jedi boss. Stand there and tank and spank AOE. It will be dead before more than three or four of the adds arrive, and you can just heal through their little explosions.

The boss that drops the AOE fire droids is interruptable. If you can interrupt those, its just another stand there and dps him down.

Optional boss is easy. Just interrupt the machine gun fire and its more stand there and dps it down. put the tank against the wall so he's still in range from the knock backs. Even still he hits hard and fast so be ready to use your tanking cool downs/relics and a medpack, but if you don't interrupt I doubt you can kill him as a fresh 50's group. Juggernauts have 5 tanking cooldowns from 10-20 seconds in length each. If you space them about 10 seconds after each one finishes, you can pretty much chain them. It's ridiculous.

Final boss is a joke. Pew pew then hit your strafe button when she pulls you in just like you do on normal.

Having a good setup is key. Easy to heal, round robin interrupts, minor movement abilities. Others, I dont know how you would do by yourself like the Colicoid war games.
