This website has lots of useful info, sometimes better than reading books. Does ET offer downloadable archive for a fee?
I have seen a macro in use that was able to gather all the posts by one user into one long thread. You could download it under the form of a zip-file. Unfortunately I am not in contact with that person anymore.
It is easy to search for all posts by someone or on certain subjects and I assume you know how to do this. Although I haven't used it, I've read good things about instapaper. These together might give you what you're looking for. http://www.instapaper.com/ Don
