Can’t edit CSS in wordpress

This might be an question with an obvious answer but I’m stumped. I want to change a couple of things on the stylesheet.css but I cannot find where it is on wordpress. Is it not showing because the author says blueowlcreative? If that’s the case how do I change that in order for me to be the author? Here is what I see when I click Theme Editor, Stylesheet:

/*
Theme Name: Aqua
Description: A business, portfolio and blog theme.
Author: BlueOwlCreative
Theme URI: http://blueowlcreative.com/wp/aqua
Author URI: http://blueowlcreative.com
Version: 1.5
License: GNU General Public License
License URI: license.txt
*/

@import url(“stylesheets/skeleton.css”);
@import url(“stylesheets/stylesheet.css”);
@import url(“stylesheets/flexslider.css”);
@import url(“stylesheets/prettyPhoto.css”);
@import url(“stylesheets/carousel.css”);

Any help would be appreciated a lot!
