Considering the Catholic Church finds no contradiction between evolution and the faith, I too would say evolutions importance to the existence/non-existence of God is overrated.
And you're somewhat misleadingly misrepresenting that Wikipedia article. It actually says that the no-conflict position is an unofficial stance of the Vatican.
It also (rather importantly neglected by your comment) says that their position is that humans are indeed special and need the existence of god. That's rather a conceited view of our species, but then this is coming from the same organization that spent much of the 13th century burning whole french villages...
as to the second point: I would assume the Pope actually knows the opinion of the church and wrote so here: http://www.ewtn.com/library/PAPALDOC/JP961022.HTM or http://www.vatican.va/holy_father/john_paul_ii/messages/pont...
As to point 3: see my response to 1 and yes, religions for the most part believe Humans are special. Being sentient tends to do that.
