Header, menu and search box questions

Hi there, Would you please show me how to: 1) Add a line between each item in the menu. I would like division in the menu bar like this website (I found on your forum): http://timewisefoundation.org.uk/ 2) Change color of header text's shadow. The default color is white (I think). 3) Change color of the text in search box. The default color is gray. My website: truchawaii.com/viet Many thanks.
