I haven't verified it completely (and I'm not going to), but what you've shown indicates that you are using a correct approach on everything, and so if you do have a mistake it is likely a "goof".
But YOU need to develop the ability and, more importantly, the habit of checking your own work. In the case of problems like this it is pretty easy -- take your solution (the logic circuit) and a clean sheet of paper and work out the truth table for it. Then compare it to the original problem.
You also have the ability to ask if the answer makes sense in other ways, too, sometimes. For instance, look at your answer to #3 and see if you can convince yourself that it is correct based on your knowledge of how 1's comp compares to signed magnitude.
