I have some code that I have adapted to run on a headless Rpi using a usb webcam, it is running a bit slow, so my questions are:
If I were to use the GPI pins with a dedicated webcam would that be faster?
Is there any way to speed up my code for Rpi?
Where can I get a Rpi webcam?
For your question about where to get a Pi camera, a new camera has recently been release. I don't know about speeding up you code, but you might want to overclock your Pi. Good luck,
