I think you have to scrape it off. Not sure though.
About the ticket, i'd fight it. Take it to court and they'll likely drop it. Just tell them that you just bought the car and haven't had a chance to take the dark tint off, which is true. Even if they don't drop the charge, they'll reduce the fee.
Then with the money you save, let that pay for some performance parts or some lighter window tint...
