Topmenu CSS & User 3 space

I'm having a tough time isolating the correct code. I want to increase the spacing between the links in the topmenu. It would seem the place to adjust this would be in the template_css.css file in the section for /* top menu */ but changing or add to the code here doesn't change the menu. I commented out the div with the logo and wanted to use the width of the page.

Also my client does not want to use the carousel. I want to place an image in the User 3 space. I tried adding and image link in the CSS to place the image, but it did not work. I edited the layout.css and tried changing the #carousel_wrap or the .carousel_module but it did not work. Where is the style for that area?

Sorry to be a pain. I appreciate your time. Thanks!

Menu: Please type "nav" as Module Tag ID for the top menu module. Module type should be list, other fields empty.

Carousel: User3 space is top menu space. I guess you want image where carousel is (module position Carousel). Simply unpublish carousel module and create new custom HTML module with image in Carousel position (modules > new > custom html).

You don't have to edit code at all. If above doesn't work you probably messed template code, so please restore it.

That worked! Thank you.
