You can extend D now using disk management ... so add the 3GB space to it. You can do it now... it's without risk.
Afterwards you can add the 9GB in front of C to C using PW. Also without risk. But do it by booting from PW bootCD. Adding space in front of partition is a little bit risky. In case of power failure... C is damaged. But PW does it very safe! Best thing to do is make backup first
