CSS not updating/Blog Feed

I am taking over editing a client’s site. and right now i have 2 issues.

One is when i edit the code in Editor and click update, I do not see the changes reflected on the site. For example, I would like to change the font/font size of the menu bar and tagline.

Another issue is making the home page correct. I would like to have the main banner image and 3 posts below it. Currently my settings in homepage settings are

-Static page
-Homepage (Set to the Home page)

But now I get this Home section at the bottom of the page.
