Tongues? James vs. Paul? Women in church?

What about people in remote locations who have never heard the gospel? And what about all those Gentiles in the Old Testament? How can believers who have died already have a resurrection body in Heaven? Or are they bodiless in Heaven or sleeping for thousands of years? What are your thoughts on James? Does he teach the Old Testament law as the means to salvation? What is the gift of tongues? Are there two kinds of tongues? What about women leading in church? Aren’t they told to always be quiet?
