RSS Feed Improvements - where to start?

[steve]

I'd like to improve the way newsreaders (like Google Reader) and FeedBurner deliver my posts.

To make it easy, I'd like have them both look the same. I would like to include the headline, author, release date and time and the first paragraph or so of the post.

If I choose the /rss/ link for the feed in the reader, it does not display the author or release date/time, but it does show the first paragraph or so.

If I choose the /rss2/ link for the feed in the reader, it displays the author name, but also displays the full post which I do not want.

The FeedBurner delivery service works fine (I so WISH Constant Contact can do this) but it does not display the date or author name.

Where can I start to get this updated/changed?

Thanks in advance!
