Well I can't help on the re-read, I only started WOT a few months ago, on book 6 now.
http://www.encyclopaedia-wot.org/ is a good place to get a quick wrap-up of each chapter. I used it a lot during book 5 as I really started to get confused (and given I have found book 5 and 6 really hard to get into until about 200 pages in and then the books seem to take off).
