Answer 1

Since you are using the bootstrap, you can add its class "navbar-fixed-top" to the menu. The example of usage you can see here
If you just need to display the already attached menu correctly on top of the rest of the content - just use CSS z-index:
.menu-wrapper {
z-index:99999;
}
UPD: use this pattern to add classes on scrolling
