Exactly which JS and CSS includes do I need?


I'm trying to get the Dialog plugin working but it looks extremely
plain. The demo page doesn't mention whether I have to include a CSS,
but I'm sure I have to: http://ui.jquery.com/demos/dialog
Where do I get the CSS or whatever for the Dialog plugin? I've
downloaded a theme and the complete jQuery UI set of files, and have
made the following references in my file (I've stripped the HTML to
make this post):
./jquery/jquery-1.3.1.js
./jquery/ui/ui.core.js
./jquery/ui/ui.dialog.js
./jquery/themes/ui.dialog.css
I'm obviously missing something, but what? More importantly, where is
the documentation that says exactly what I need to include? I can't
find it anywhere and I'm sick of trying to pick and choose from
viewing the source of various demos (which is obviously a painful
process).
Thanks.
