hover color css in sidebar widget

Hi, This post is about changing hover style and color of links in sidebar widgets and content. - I'd like to change the Sidebar Widget Link HOVER Color which by default is green to #e17c05. - same question for the paging at the bottom of featured page slider. - I'd like the links in content to be bold and hover not underlined but different color. Could you please help me to custom the css? Thanks a lot http://geoprisms.org/wpdemo/
