428295 Reduce webpage loading speed

Hi, I have a website [login to view URL] and i want to reduce the speed that the pages load at. They are loading very slow and my google account is recommending that i reduce the speed that pages load at. I will want the programmer to view all recommendations on my Google webmaster account and impliment all recommendations. Simple project for the right person. Site is a Joomla site. Google is recommending "enable gzip compression" "Combine external javascript" and "Combine external CSS". All items that will reduce the loading time of all pages must be implimented. I will test before and after project begins. Feel free to ask questions. Thanks, Steve
