The link you've mentioned has information for CSS 2006 which has been held in the month of May 2006. We're waiting for the result of it at this moment.
As far as CSS 2007 is concerned, month has been announced for it, but no particular date. For further information keep an eye on news papers and on forum's board. Similarly, the process of submission of forms has not be started till yet. As soon as FPSC announces the date for exam and for the submission of forms, we'll update the forum with latest news, so keep on visiting the forum.
And yes the site you mentioned in the link is not the official website of FPSC, You can have direct access to FPSC over here
www.fpsc.gov.pk
