Changing the drop down [sub] menu look

I wanted to do the following to the drop down menu:

1. Change the background to white
2. Make the bottom border a color
3. When hovering, make the top, right and left border a color
4. Make the font color and hover match the main menu

It would essentially act like the drop down submenu in the Luke + Sara theme. How should I go about implementing these items?

I also would like the footer menu to have the hover color match the main menu and remove the | in front of Home.
