This particular prophesy is fairly interesting, as God establishes a metaphor of an underlying struggle between the different individuals within a family. Ironically, this is somewhat freeing, as it allows a person to decide against others in their family (imagine if you can't do that), and thus create the conflict (there was no family before this, just a man and a woman, so there would be no point in giving it earlier. Plus, you must have to understand the psycological impact on the pair and what it may do to humble them.) Generally, as a son with parents I understand the kind of dislike a child may have with the parents whose role is to make oneself more controled. 
For the far latter, the metaphor would relate to potentially "a Son of Man (the metaphorical seed)" and how something will be done to "bruise (or crush, as some translations have put it)" the head of the Serpent (Satan/Accuser/etc.). This "Son of Man" potentially ends up being a "Son of God," and crushes the "head" of the Serpent when he dies and provides the sacrifice for all the sins of the world. Such a blow is crushing since not only would it allow "those who have fallen short of God" in their sin to escape Hell, it also establishes a new covenant with not only the Jews but also the Gentiles as well. Of course, the striking of the heel is often interpreted as how the "Serpent" is low and impedes a person's progression towards the real goal of reaching God, which is basically the only thing he focuses on. Previous to this, the Serpent actively spoke to Eve in the garden; now, he can only impede their walk with God. 
As for a more clear prophesy, I found this:
Nahum; basically "an oracle concerning Nineveh"
Nahum 1:7-8
The Lord is good, a refuge in times of trouble. He cares for those who trust in him, but with an overwhelming flood he will make and end of [Nineveh]; he will pursue his foes into darkness.
Have fun!
