Magazine: Removing search bar and compacting white space

I would like to remove the search bar from the top of my theme. This way my logo will be at the top of the page and content will be moved up.

Additionally, I am looking to eliminate as much white space as possible between the page content, widget sidebar, and menus. All the white space in between I would like to bring down as much as possible.

Essentially, I am looking to "crunch" everything together if possible. How can I make both of these edits? Thanks for your help.
