If you could post pics of the dots, that would help. From what you have described, it sounds like a bad digitizer. Easy and cheap to fix. The white dots could be marks on the LCD, but without pics its not possible to say. I would start with changing the digitzer and would inspect the LCD while I was in there. Chances are that the spots are on the digi and the LCD is fine but the LCD could have also been damaged and need replacing.
