It's laudable that you are paying attention to caching, but you don't compile all your files in to one file. It seems like you could pick up a lot ground here by at least concating all css into one file, and js in to one file.
Also you could load jquery from the Google AJAX API endpoint. That way the users has a higher chance of having already loaded jQuery.
Also using the same CSS/JS products across multiple pages would help.
