Change template backgrounds

Hello again, good work.
I have a few question abaut custom the template.

1) How do I can erase the background at the top of the template? and footer?

2) How do I can delete or change the background of Articles (picture of the world)?

3) I Install the template as a quickstart mode, but the module Hotbars I can not find it.

Thsnkd.

1) in template_css.css

.toprow {
padding: 20px 0;
background: url(../images/custom/bg1.jpg);
background-position: 0px 0px;
}

remove (or modify background property)

2) also in template_css.css

.contentrow {
padding: 70px 0;
background: url(../images/custom/world.jpg) no-repeat center;
}

remove (or modify background property)

3) there should be module named like that (hot bars) in module manager
