Good observation, Sarah.  Although the episode of Paris hitting Achilles in the foot, his only vulnerable spot, is never mentioned in the Iliad, this episode certainly seems to foreshadow it, and fits in with the typology of warriors in the poem-- the archers are less noble than the warriors who fight hand to hand with spears or swords.  Paris, who is clearly portrayed as a coward, has the bow as his weapon, as does Pandarus, who (albeit at Athena's instigation) breaks the truce by using his bow.  The bow seems to be a weapon associated with treachery (so it is notable that the bow is Odysseus' weapon in the Odyssey).

Check out the link to an excerpt from Sebastian Junger's War on Thetis Speaks. It may give you some ideas for Writing Assignment #2 (posted under Assignments the UBLearns, in case you have forgotten about it!).
