All of your arguments about Mary lack sense.  You point out the scripture when Jesus says:  But he said: Yea rather, blessed are they who hear the word of God, and keep it. (Lk 11:28) What does this say about Mary?  In Luke we see the angel Gabriel appear to Zachary and then to Mary.  When Zachary hears the word, he has doubts, so he is punished by the angel: "And behold, thou shalt be dumb, and shalt not be able to speak until the day wherein these things shall come to pass, because thou hast not believed my words, which shall be fulfilled in their time." (Lk 1:20) In contrast, when the angel appears to Mary, she submits herself to the will of God: "And Mary said: Behold  2000   the handmaid of the Lord; be it done to me according to thy word. And the angel departed from her."  (Lk 1:38) She is perfectly obedient and humble.  She is going to bear the Son of God, but she refers to herself as a lowly handmaid. So when Jesus is saying "rather, blessed are they who hear the word of God, and keep it" He is pointing out that Mary is blessed not only because She gave birth to Jesus, but also because she submits herself perfectly to God.    This is why Jesus listens to Mary's prayers and why He set Mary above all the angels.  Jesus did His first public miracle at the behest of His Mother. Mary is a the most powerful Saint in heaven. God set her above the devil.  She is the fulfillment of the first prophecy in the Bible:  Gen 3:15 "I will put enmities between thee and the woman, and thy seed and her seed: she shall crush thy head, and thou shalt lie in wait for her heel." It would be nothing for Jesus to crush the devil's head.  Jesus is God. If He wanted to, he could crush the devil as easily as snapping his fingers. But to humiliate the devil, God appointed a woman to defeat him.  We see this over and over in the OT: Deborah drives the tent peg into the head of Sisera; a certain woman casting a piece of a millstone from above, dashed it against the head of Abimelech, and broke his skull. (Judges 9:53); Judith cuts off the head of Holferness. All of these events prefigure the role that God chose for Mary to fulfill.
