It looks like you have the pages widget set in the footer widget area. You can change that in Appearance > Widgets.

What code did you try to edit out?

By putting the code in the selector above it will only take effect if the screen is 960px or larger in width.
So adding your width attribute like the code below will limit the width to 70% if the screen is 960px or more, otherwise it reverts to the default settings.

@media screen and (min-width: 960px) {

.entry-content {
    max-width: 70%;
}

}

Thats not actually part of the theme but I was able to replicate it with the code below.
Instal a plug-in like Simple Custom CSS and then enter the code.

#content {
    background-image: url(http://upload.wikimedia.org/wikipedia/commons/0/01/Polish_Wikinews_header_image.png);
    background-repeat: no-repeat;
    background-size: 100%;
    background-color: white;
    background-position: 0 30px;
}

article {
    padding-top: 30%;
}

You will need to change the URL to your image and adjust the padding-top percentage to your liking.

To remove the pattern:

.jumbotron:after {
    background: url();
}
.footer-jumbotron:after {
    background: url();
}

To change the color:

.jumbotron {
    background: #0088cc;
}
.footer-jumbotron {
    background: #0088cc;
}

To remove header portion:

.jumbotron {
    display:none;
}

}

#footer .wrap {
margin: 0 0 0 auto;
}

Install a plug-in like Simple Custom CSS then add this code for the titles and change the colors to your liking.

.entry-title a {
    color: #0000ff;
}
.entry-title a:hover {
    text-decoration: none;
    color: #ff0000;
}
