Missing MacBook Air cables

Having less than two months ago become the proud owner of a 1.8GHz Mac Air. Then I managed to have the power leads and assorted cables pinched from my car. I'm having a nightmare trying to purchase replacement cables.

I have been to Apple web-site and searched a few other places and have been unsuccesful in finding any replacement! can any of you good people point me in the right direction of as to were to purchase?
