St Peters on Tryon is the closet to 6th st. There is another one in Dilworth about 2 miles away. It is the cathedral for the area. St. Patrick's Cathedral, 1621 Dilworth Rd E. Hope that helps get your bearings.
I am not sure what yoru question is in regards to Catholic Church. There are a few in the Charlotte area and soem in plans of being built. Unlike up north ( i figure based on the user name that you are from New Jersey) where they are on every street corner.... here they tend to be larger and more spread out....
