How do I remove the Title of each page from the body of the pages?

When I log into my site http://66.147.244.177/~earthsc8, I want to remove the title of the page as it appears in the text of the body. if you click on the about us, it says about us in the page, as well as the menu. I'm new to WordPress and trying to understand this. I also want to know if I can add sliders on the interior pages or not. my client wants to showcase their work but I don't want it as a gallery, want a little movement to it. Also does anyone know how to get rid of the blank white space at the top of the pages? I don't know what goes there but there is a dashed line and it looks bad. I attached a few images to help. The outdoor one shows that outdoor is my header in the paragraph but the outdoor products shows up above it as it's the title of my page. Also the archives and comments and search bars are on there. ugh, I can't get rid of those either

 

Hello,

Paste the following code in your Custom CSS
(Appearance -> Theme Options -> Styling Options -> Custom CSS)

Code:

.page-content .fullwidth h1.page-title {
display: none;
}
.social-links {
display: none;
}

For the slide show,
you can try WP Slider Plugin, you can download it from the link given below
Download it from the link given below and install it from the Plugins panel (Plugins ->Add New ->Upload) in your Dashboard.

For the sidebar issue on the page,
go to the Pages > All Pages panel in your dashboard and edit those pages in which the sidebar (i.e archives, comments and search bars) is displaying
and then select the "Fullwidth page" template from the Page Attribute section.

 

Thank you!
