IMOPIOS,
1) The passage illustrates the Queen Mother's position as an intercessor. Solomon doesn't get mad when she asks to ask a favor ... he gets mad when the favor asked is an evil one.
2) that foreshadowing fits very neatly with Adam's disobedience foreshadowing Christ's obedience to the Father. And when Mary does act as an intercessor (at Cana), her request is good, and Jesus grants it in a big way.
The Cana reference is problematic for the opposite reason. The request is good, and Jesus does grant it, but he certainly acts like her even asking the question is less than accceptable, like he is tolerating her request rather than graciously hearing and granting her request.
