Menubar Styling Help

Hi all,

I would like to duplicate some of what I see in this menu here:
http://www.basementtechnologies.com/

First, how/where can I create a create a gradient for the menu items? Can that be done in CSS or do I need to create an image as a rollover?

Second, is there a way in CSS to make the menu "roll" down like in the example above?

Here is the site I am working on:

I would also like to get rid of the double down arrow in my menubar. I hope this is an option in a future release. I would love to see this in the controls as "use down arrow" yes/no or better yet, use this icon as a down arrow -- kind of like the option for logo and favicon.

Thanks for any help!
:D
