Black22 on "Changing Size of Logo and Moving Search Button"

Hello again,

http://serwer1381464.home.pl/autoinstalator/wordpress/ Page (I know, looks terrible, but because everything is random and just testing possibilities of WordPress for now with custom style.css)

I would like to achieve two things.

1. Streching Logo to left/right/up side of that green border. For now as u see it's centered. I tried to achieve by messing with header but without any luck for now.

2. Moving this search bar to the right side od nav menu and making it little smaller (weight/height) to make it more fit.
I got the search bar by adding to style.css

#branding .only-search + #access div {
    padding-right: 10px;
}

and

#s {
background-color: #fff;

color: #000;
border: 5px solid #ff7700
}

Anyone has any idea how to get these two things?

Thanks for every answer!
