Is the name of the church Important?

Does the name of the church matter?

Why don't most churches believe in speaking in tongues? Only the holiness churches?
Do you believe in tongues today?
Do you have to say anything (Ex: I baptize you in the name of the Father, the Son, and the Holy Ghost/I baptize you in the name of Jesus) when you baptize someone for them to be saved?
