The patched kernel will help you in avoiding dropouts in sound (xruns is
what they are called in JACK). It won't help you to get lower latency per
se, but it might help if you get these dropouts at low latency settings.

The camera problem sounds weird, could be caused by poor lighting
conditions, or there is a problem with the camera. We have used
webcams under all systems for the reacTable and latency was good.
