Hey Deacon,
It's good so see ya over here. We could use a few more good catholic posters on these parts.
As for the devotion to Mary, she has a unique place in salvation history. God chose her among all people to be his mother. Frankly, Catholics are impressed by this and we cannot understand why other Christians, except the Orthodox, are not. She had a unique relationship with Jesus.
I'm impressed too. She certainly played a unique role in the salvation process by birthing and raising our Lord, however I don't see the whole reasoning behind immaculate conception or the fuss with praying or requesting her favors as opposed to anyone else for that matter.
