You need to play with the z-index to bring elements back/fwd, when something like that happens. The submenu, for example:
Code:
.navigation ul.menu li ul.sub-menu {
z-index: 10;
}
The pagination issue: you need to be more specific, if you have other anchors on the same container
.modelicon
Change
.modelicon a:first-of-type
to
.modelicon > ul a:first-of-type
