Will you be so kind as to answer these ?'s Catholics?

A few questions for you if you're Catholic. Where is it in the Bible, the book that Christianity is based on, to pray to Mary or any other saint. Where is it in the Bible that a Priest must remain celibate? Doesn't the Bible teach not to use VAIN repetitions of prayers? I have seen and heard catholics repeat the same prayers over and over again in one setting. Where does the Bible teach that one must confess their sins to the priest instead of confessing them to Jesus, the mediator between God and man? When did Jesus say the church should have a figurehead OTHER than HIM, like the Pope? Where did Jesus or anyone else speak of a place called purgatory, and where is it taught that sins can pretty much be ranked? Didn't Jesus say no sin will enter into the gates of Heaven? No disrespect, but there just seem to be many traditions and beliefs which are not Biblically based.
