Umm that sucks. For your first question I would get some black car wax and wax over the fairing a few times with it really good. That's probably the best you'll be able to do to make it look "normal" again.
For the second question, you need to be more clear - blackish fluid is too vague. It's either oil, oil and gas, or brake fluid. smell it to find out
