I can't be specific with your camera as I don't own one, but generally, you need to either increase the ISO, and/or open up the aperture to the point where then slowest shutter speed is 1/60th of a second. That is about as good as you can hand hold a wide-medium telephoto lens before you get camera shake in your photos.
Most on board flashes are rubbish, so either get a more powerful external flash unit, or get a faster lens, or take a tripod, or get a camera that can handle better low light situations.
