It would seem the light levels in the room are just too low to get clean sharp results. The white balance looks a fair bit better although still slightly off. You new shutter speeds are 1/15th and whilst that is better than 1/8th it still isn't going to be very steady, especially at the 70mm focal length you are shooting at. I presume F4 was your largest aperture then? If so, your only option is to add more light (window, room light or a flash) unless you can get to ISO6400? Try not zooming in as far too. You'll have a better change of not getting camera shake if you are at your widest focal length.
