Search engine issues

Hi, I’ve recently discovered that when I search my website, the google dropdown that shows what pages are on the site (work, weddings etc) provides me with a couple of links that go to parts of my site I don’t seem to be able to edit. The links are admin ( http://www.winternetphotography.co.uk/?author=1) and news (www.winternetphotography.co.uk/?cat=3) I need to get rid of them or change them or get google to blow them away somehow.
My mental patience is running as thin as my hair, and I need help before I have to be sectioned.
Help!
thanks,
Elliot
