I don't know much about photography, but two suggestions:
1.Is it possible to put your camera onto a high ISO setting? Most digital cameras probably adjust this automatically, but it might be worth having a little play. AN ISO of 1600, say, might reduce the blur/camera shake, though at the expense of detail and an increased graininess.
2. How are you holding the camera? I can never get indoor pics worth a damn without having the camera resting on something. One of those little bendy tripods is great, but a table or back of a sofa can help. Even leaning against something can sometimes help.
