2) I would hope that in your studies you have heard of "Archetypes", Foreshadowing in the OT directly pointing to items in the NT. Adam, Noah, Moses, David, etc... were human Archetypes of Christ. The Ten Commandments, Manna, and Aaron's staff were all inanimate Archetypes.
A careful open minded study of the OT will also see Human Archetypes of Mary, these include; Ruth, Ester, Judith, and Bathsheba. They will also see two inanimate archetypes. The first is Noah's Ark, and the second is the Ark of the Covenant.
The thing with Archetypes is that they are all lessor foreshadows of their fulfillment. The description of the materials and construction of the man made Ark of the Covenant is a pale imitation of the perfection achieved by God in Mary, and this is confirmed in Revelation chapters 11/12.
It is still a greeting. Most of the major translations go with Greetings. Less than half translate as Hail. In either case, it's a greeting.
We never have a hint of anyone in the OT or NT referring to Mary being an archetype or the other way around.
