I figured out the basics for customizing themes and was able to make the Original Author field show. While reading PHPTemplate docs I found that quite a few modules (e.g. Organic Groups) come with included tpl files, exactly because of unique usability requirements.
I think it would be valuable to create default PHP templates for aggregator2 as well.

buddaWhat specific information would you like displayed in the template?
You can easily created a node-aggregator2_item.tpl.php and then do a
var_dump($node);to see what data is available to display.
