Layout customization questions: Website Title& Main Menu

Hi, I have a couple of questions regarding the layout customization. My website is here http://box5684.temp.domains/~johnspo3/sample-page/ I need to: 1. Reduce the top/bottom margin for my Website Title section - make it narrower; 2. "Spread" the top menu options (justify), or to increase the space between the menu options. Thank you,
