These are all really issues that you should discuss with your pdoc. What is it exactly that you hope to gain from and ADHD diagnosis? Medication?

If you are not struggling academically, have you considered an ADHD or organization coach? They would be able to help you with organization, time management, etc. They would also possibly help with social skills.

As for sleep, it is possible that you might just be a night owl?

I wonder if a melatonin tablet might help you fall asleep? Once you get on a regular sleep schedule, it might be easier for you to wake up feeling rested.
