Basic questions about themes.

Basic questions about themes.

Hello all,

I am fairly new to jQuery and just started using jQuery UI and I had a couple of questions about themes. I wanted to incorporate some jQuery UI components, particularly datepicker, into the site I am building but have run into a few snags. I already have links to the jQuery core and jQuery Ui already in my file like this:
  1. <script type="text/javascript" src="http://www.google.com/jsapi"></script>
    <script type="text/javascript">
     //<![CDATA[
        google.load("jquery", "1.3");
        google.load("jqueryui", "1.7");
      //]]>
    </script>







 so when I download the theme I don't have any of the components checked. I then take the jquery-ui-1.8.1.custom.css file and link it to my page. I take the contents of the images folder and put it into my already existing images folder. The datepicker sort of works, some of the colors from the theme are there but it gets strange when I mouse over a button to change the month, it sort of jumps around and I can't click on the button. I tried this with two seperate themes and I am still getting the same problem.

My questions are, am I downloading this correctly? Should I not be picking any specific widgets and components because I am already linking to them? Is there something I am missing? Does anyone know why the datepicker is behaving this way? Any information would be very much appreciated. Thanks much!
