The box-shadows are applied using the .ui-shadow class. So editing that CSS class like below will remove the shadows:

<style>
[data-role="header"] a.ui-shadow {
    box-shadow: none ;
}
</style>

This will remove the box-shadow for any link with the .ui-shadow class that is located inside the data-role="header" element.

Here is a link to an updated version of your fiddle: http://jsfiddle.net/9S3a3/14/

On a side note, I remove the text and box shadow for most elements as it helps improve performance on mobile devices quite a lot.

I didn't get which buttons are you asking about, however, correct me if I am wrong. Add

#nav_header {
    border-bottom: none;
}

to your CSS (http://jsfiddle.net/9S3a3/13/) to remove the shadow (border) under the Featured, Near, New buttons.
