What can I sue my painter for legally?

You can get all of your money back plus all of the damages. Just doent everything carefully. Take detailed pictures and get receipts for all of the damaged furniture and CD changer. Take photos of the carpet stain and get an estimate to get it cleaned professionally. Get an estimate to get the ceiling repainted too. Then if everything totals less than the maximum you can get at small claims court ($5k in some states, $3k in others) you can go to small claims court. Otherwise you will have to go to regular court and may need legal help filing the right doents. But as long as you doent everything you should get the judgement. Getting her to actually pay it is another thing. Good luck.
