Header, Footer Borders.etc

Hi

I am using this theme and want to know the CSS that I can use to

1) Change the color of the boarders/divider lines of the header/footer, etc. These lines are currently light gray.
2) Width of the border/dividers, etc.
3) Menu size and menu fonts (bold,etc), and menu color
4) Color of the search bar button which is currently black
5) color and border of the email subscription box and button
6) Color and background of the random quote widget.

Is there any way I can remove the entire line at the bottom that starts with the word copywrite……
