The screaming brakes; why would you complain about something you knew before you bought it? If you don't like a bike with screaming brakes, don't buy it. Simple.
The fork has gone soft after a month of lots of use, so that's now his problem. There is no warranty on second hand items. As a buyer you have to do your due diligence and ask questions, inspect the item, etc. Would he have come to you a day after he bought the bike to complain about the fork, I'd say it's probably a different story.
You didn't lie about the bike's condition or omitted any hidden problems, right? So you didn't do anything wrong and therefor cannot be blamed.
Of course this is your side of the story, he has his (which we haven't heard, so far).
