I just thought that I’d let you know that my wife and I are really enjoying your Revelation reading assignments. What we like to do is read the assigned passage from 2 or 3 different translations (usually the ESV, TNIV and the Message)—this seems to help us not only understand the words of the letters, but also the feel and tone. There’s a pretty good chapter on Revelation in How to Read the Bible for All Its Worth—you may want to add this to your recommendation list.
I heartily agree with his recommendation on Chap 13 in Gordon Fee's book, How To Read the Bible for All Its Worth. It is one of my favorites. You may want to check it out.
