Hey, great to hear about your success! My numbers are still strong, and they are getting better as I'm making more wallpapers. In fact according to StartApp's policy, you get to negotiate a new rate once you reach 300k installs. Your ratings are bound to take a hit as you add ads. Most people don't like ads, and would prefer to have the app free with no strings attached, especially if this is what they were used to before. You will also miss out on users who don't install apps that have ads, or request a number of permissions. But that's just how it works. We have to make money somehow too, right?
