Personally, I don’t find the first two goals to be particularly useful. I find it easy to scan for new comments by scrolling down the page looking for the green left highlight. I also find myself always wanting to scroll down to get the actual comment in context.
However, I am a very big fan of the idea to allow the author to provide a summary. Honestly, I think it may even be a good idea to require a summary for sufficiently long posts. I suspect that requiring a summary will a) be great for users, and b) not meet too much resistance from writers.
