No, not actually. Don't confuse rumors with actual, professed dogmas.
And we also disagree that Mary is omnipresent and omniscient. Only God is, and only God can hear the prayers of millions at the same time. Mary is in one place, and cannot multitask sufficiently to hear all the prayers directed toward her.
So you know what is possible for human who have attained the status of Beiing in the Presence of God? (We call this the Beatific Vision.) You know that after the death of the body, Christian saints cease to be caring, involved members of the lives of those of us left on earth?

Again, no disrespect for this past Pope, but it's important not to let false doctrine go unresponded-to:
1. Pope Benedict XV, in 1918 - “Mary suffered with Christ and nearly died with Him when He died, thus she may rightly be said to have redeemed the human race with Christ.”
2. Pope Pius XI, in 1923 - “The virgin of sorrows shared the work of redemption with Jesus Christ.”
3. Pope Leo XIII, in 1891 – “No one can approach Christ except through His mother.”
4. The Catechism, in the Sunday Missal (Catholic Catechism) says, “My salvation depends on Mary’s mediation and union with Christ, because of her exalted position as Mediatrix of all grace.”
5. Vatican II, said, “Mary’s intercession continues to win for us the gift of eternal salvation.”
One nice thing about "Protestant" leaders is that they're not infallable, and can admit they were wrong.
