2-I edited the code in your custom css box, that controls this screen dimansion to this:

@media (max-width: 1100px) and (min-width: 981px){
.textbar .btn-bt { left: 75% !important;}
.textbar h2 { 
    margin-bottom: 10px !important;

}
.header_1 nav .menu > li {
    margin-right: -1px !important;

}

4-The Revolution and layer slider are independent from theme. They are slider plugins used only for slider. You can do what you want with them. It won’t affect theme.
