I am a recent grad, had my 1st interview 2 weeks ago and was offered a position today. My coverletter and resume look similar to yours except that I did not add my clinical experience. I do not think it is necessary because most nursing students go through the same rotations. If you wanted to bulk up your resume, maybe you could expand on your work experience. I agree with AllInRN about the education, before I graduated I applied for a few jobs and that is how I was instructed to word it. I would not add an objective as I was told to remove mine and I also don't have a professional goal. I was asked in my interview what my future goal is. Good luck!
