FAR AWAY= At a distance.

HER FATHER'S DAUGHTER= That's herself, because every girl is, as they say, daddy's daughter (meaning that their father adores them). This expression here suggests it could be some out-of-body-experience, like she's working there but her spirit is far away. Or a reference to a long-past lost innocent childhood, when she was that cute baby, her daddy's daughter. Also notice that she doesn't pronounce the H in HER, so "from her" sounds /fromə/.

WHAT I GOT TO DO= What I've got to do = what I have to do = what I must do.

ROCKABYE= It's the beginning of the most famous English lullaby (a song to make children sleep) You can listen to it here. To rock is to move something (the baby) from side to side, and in child language "go bye bye" means "go to sleep", so "rockabye" suggests the idea of rocking the baby to sleep.
