Catholics do not worship Mary. This is a common mistake among non-Catholics and even some nominal Catholics that prayer = worship. Catholics ask Mary and the Saints, whom we believe to be alive in Heaven to pray for us. I know a lot of people will hear the prayer such as the 'Hail Mary' and think that it is worshiping her, but veneration, as defined by the Church is not the same as worship due to God and God alone. It is no different that when person asks a friend or relative to pray for them. Many non-Catholics also assume that because they think we "pray to" Mary, that we do not pray to God. That is also not true. The entire Mass is a prayer and offering to God The Father.
No, it is not rude to ask questions :) The major difference between Catholicism and protestant groups is that Catholicism is historically backed, whereas the Governing Body is not. Each Catholic Bishop can trace his spiritual roots/ancestors all the way to the Apostles themselves. This is called Apostolic Succession and it gives validation to the doctrines and practices which have been carried forth from the 1st century; a quick read of The Divine Liturgy of St. James or The Didache gives the Church extremely powerful evidence that it is the Church of the 1st century. With this historical tie to the 1st century comes authority, since Catholics believe that Jesus made Peter the first Pope (well, the word Pope didn't come about until later, but just for the sake of the discussion here...). Following Peter was Linus, Cletus, Clement, etc How far back can the Governing Body go? Where is their authority?
Since the Bible was compiled by Catholics, for Catholics, the Church has credibility in how it is to be interpreted. With the Church, there is at least a sense of 'the historical'; with the JWs, I get the distinct inpression that they are making it up as they go along. So yes, I do trust the Pope and the Magesterium when it comes to the faith.
As far as the paganism is concerned, I think that the JWs get tripped up on this. If they want to claim certain things such as veneration of Mary is akin to pagan goddess worship, Christmas is Saturnalia, and the Trinity, then they must compare the rest of Christianity as well, such as Virgin Birth, Resurrection, the Son of God, etc. They do not understand the distinct natures of biblical literature vs. mythical/pagan literature.
