Whoa! Mark's doing a site review?

Where to start...

First thing - you answered your own question. Robots don't follow javascript links. You aren't using any <a href> tags...

Second, just a quick glance at your code shows A LOT of empty tags. Here's a snippet of code from your site:

          <tr>

            <td width="35%">&nbsp;</td>



            <td width="31%">

            <p align="center">&nbsp;</td>

            <td width="34%">&nbsp;</td>

          </tr>

          <tr>

            <td width="35%">&nbsp;</td>

            <td width="31%">&nbsp;</td>

            <td width="34%">&nbsp;</td>

          </tr>

I know why there are so many &nbsp; (no-break space, A.K.A. empty)....
...you are using tables for layout, when you should be using CSS. CSS is fairly easy to learn, http://www.w3schools.com/css/default.asp - read and apply.

If you're just starting out with CSS, a really good place to get free, W3C xHTML/CSS Compliant templates is here: http://www.oswd.org

Third, colors. Wow. Simplicity is usually key when it comes to a website (look at Google's homepage). There are tons and tons of free javascript/php/ajax scripts available online. It seems you have found this out already. However, limit yourself. You're using javascript nav menus, news boxes, scrolling photos - calm it down some.

I don't see a very clear 'Call To Action'. Again, look at Google. It is blatantly obvious what they want you to do - SEARCH. They even put the cursor in the search box for you, so the user doesn't have to click there first. You want to direct your users where you want them to go. Everything jumbled together makes it quite easy to miss important info and difficult for users to find where to go next. Nothing to pique their interest, so they leave.

A lot of movement distracts the visitor as well. You have scrolling pictures, flashy news stuff, and menus that pop open when you mouse over the navigation. Way too much, you'll lose visitors because everything's too busy.

Not trying to be harsh, just throwing in my 2 cents.

One last thing - using justified (align: justify) text can make it hard to read sometimes, IMO. That, and use the same font throughout everything (logo excluded). It looks like you use a different font for the top navigation (which are images, should be done in CSS), left navigation, body text, and images. It's OK to use different fonts, but not a different font for each part of the page.

Add some meta tags - description, keywords, etc.
