sub-menu background color

Hello,
1. is there an area in theme options to change the background color of the sub-menu? currently it is black. I also would like a divider between each sub-menu within that dropdown.
2. there seems to be a large space between the sub-menu and the menu title tab (custom link). Can this be brought up closer to the menu tab.

thank you!
