I suggest getting rid of all the js.
Remove mootools, remove the slider tab at the top, remove slimbox.
You can probably cut your css in half by removing all the unneeded styles in the css files (module positions etc).
Turn on gzip encoding in the joomla config page. (hopefully your server supports gzip).
My first check at pingdom.com showed that the site took 17seconds to load. However, a refresh moments later showed only a 5 second load time. This would indicate that it is more an issue of the database having trouble processing all those queries. I would suggest checking out the ircmaxell pagecache component over at extensions.joomla.org. It will store and serve a static version of your site pages to visitors. You should be able to set it to update the cached page every 10mins or so.
Hopefully this helps.
GollumX - Thanks very much for your comments. Yeah, I realise that the issue is the load time from the server processing all of the JS.
But is there a straight forward way to sieve out whats worth keeping and whats ok to dump if one isn't proficient in the area.?
Thanks again thou, your comments will definately provide a guide map for making necessary changes
