In your template CSS ( templates/theme580/css/template.css ), you have the code:
.container ul li a, #content ul li a:hover, #content .module ul li a, #content .module ul li a:hover {
color: #3BACE5;
font-size: 13px;
line-height: 27px;
text-decoration: underline;
font-weight: bold;
}
Please remove the font-weight: bold; from there and it should be ok.
For the display quantity dropdown, you will have to go in the menu Display->Views and edit the file listing_div of the view category. There, you will be able to change :
if($this->params->get('show_limit') && $this->pageInfo->elements->total){
to
if($this->params->get('show_limit') && $this->pageInfo->elements->total>$this->params->get('limit')){
