3 Homepage issues

Hi, Firstly, on my homepage http://www.bradcorporation.com I have two menus unnecessarily highlighted where I only need the 'News' tab highlighted. Secondly, at the end of the menu bar there is little gap. Any way to get rid of that space? Finally, I can't get the same widgets to show on the homepage as they do on all the other pages. Those missing widgets happen to be downloaded plugins for Twitter and Instagram. I've tried to solve these issue but with no luck. Any help appreciated. Thanks Mike
