Why did you put them there??

You could have used EZ-pages, I'd suggest you remove them, and use the EZ-pages instead, and you can then style the EZ-pages.

In order to find the elements to style, if you haven't yet done so, use firefox, and ownload the extensions firebug, and web developer.

I.e. your side box links case you could add thios to your stylesheet

#navColumnOneWrapper a, #navColumnTwoWrapper a {
color: #F00
}

With the above mentioned tools you could find out the single boxes, and style each box differently if you wish.
