@seoguy9999, I think you are correct on most of points mainly "Pages assembled from small pieces of content from your own site".
I've several pages with tags and when you click on these pages it shows all the topics for that tag(kind of Stackoverflow tags). I've around 16000 tags for 2000 articles. I also have some small pieces of content. I've decided to remove these pages from Sitemaps, block google from crawling these pages. Not sure I need to do reconsideration option. I will wait and see if this helps. My competitors are doing great after this update, they don't have these many pages indexed. I think number of quality pages indexed in Google is the key to solve this problem.
Coming to your point about "repetitive elements on each page", if you look at answers.com, for every question at the end of the page they add "Our contributors said this page should be displayed for the questions below" and generate 10 variations of the same subject, but they are doing fine.
