Chatty, I use The New Revised Standard Version, but it's a Life Application Bible. It's similar to your's, but at the bottom of each page there's a modern day interpretation which is extremely helpful for me.

For more verses about tongues check out
James 3:2,3
3:6
3:8

Also, if anyone is interested perhaps we could do a private forum Bible Study. Pick a book of the Bible and post about it each day?
