How to get rid of borders

Hello, I am building this site under the subdomain:
nancylynntoolan.artazine.org using wordpress.
I just started working with the Wordplus theme because I like the simplicity of it.
Can you please look at the site and tell me where the code is to remove the border around the content area as well as the border around the subnavigation menus?

I have been through the code over and over in the stylesheet.css and wordplus-rtl.css and have been able to edit everything but these two items. I would also like to remove the search and rss feed ability. Can you point me in the right direction?

Thank you!
