You'll also discover that you can't live without jQuery. It's a crucial piece to almost any web application. And since it's footprint is so small you can get away with including on most if not all pages.

jQuery UI however is heavier with css and images. It can also be difficult to get the style to work with existing applications. I find myself using jQuery UI components some of the time and jQuery nearly all the time.
