Page body extending into sidebar & menu not extending far enough


I'm not sure if this is theme oriented, or just a WP issue. Any help would be appreciated.

If you go to this page there are a couple of things I'd like to fix.

First, as you can see, where I have button points the text and image are extending into the sidebar. I have this happening on another page as well. Narrowing the body area didn't help at all.

Second, the last menu item in the menu bar dropped down to another line, but there's still plenty of room to include it. How can I edit this so that all tabs are included on this bar?

Thanks for any help!
