Small Issues With Wordpres Theme?

Im having lots of tiny small issues with my theme, does anyone know how to fix any of the following?

Website: http://1196.b.hostable.me/

~For one, at the very top there is a tan bar, not sure why that is there its not shown in your demo.

~Also, when you hover your mouse over the “truck selection” tab on the menu bar, you can not click on of the drop down options, as it quickly disappears before you can put your mouse on it?

~Also, Im not sure how to work the 3 display tabs at the bottom, I want them to just be a preview small summary and image of the page that it links to you know? Heres what I mean: http://postimage.org/image/dd55p0v8/ whatever I add to the actual page it adds to the small 3 previews shown there, so not sure about that.

~Also If you notice when you go to any other page the sidebar is broken, It says “Catchable fatal error: Object of class WP_Error could not be converted to string in /home/b1196hos/public_html/wp-content/themes/webfolio_wp/webfolio/sidebar.php on line 8”

~Last but not least, at the very footer of the theme where it repeats the top menu bar, the issue is that it is expanding the sub pages, messing of the look and sizing, see it under “truck selection”.
