I'm not sure how to install a Phillips Webcam module 'cos I don't own one, but ntfs isn't in Fedora at the moment (I think).
Try these rpms for the ntfs driver, I know they are for FC2, but they may work for FC3.
i386 (if you've got a nice fast processor, try the one at the bottom)
Try a search on google for 'pwc linux' or 'pwc Fedora Core 2' and stuff like that, if you find the source code for it try compiling it once you've installed the kernel-devel rpms. If you find a rpm for Fedora then cool!
