Your ISO looks like it's too high. Take it off auto and put it on the lowest setting. It should fix the blurriness and graininess.
If you want your pictures to be cooler, you're going to need a cooler light. Find one that shine white instead of yellow, like a daylight bulb. Though, your white balance may be off, if it's on auto, try putting it on incandescent. If it's still warm, try gray carding it.
