I think you will be in great shape to apply. The great part of the nuke pipeline is they actively pursue young men and women from A school to attend USNA. You have the stats. So the bottom line is to knock it out of the park in PT, school academics, be a leader, show maturity, support your shipmates. They want to see that you not only have the chops to handle the academics, but have the maturity and leadership skills to develop into an officer.
USNA has an active duty part to their admissions website that references the OPNAVINST that will detail how to apply. There is a checklist on the site. With the nuke pipeline they send in a dozen or more applications each year so I am sure they are familiar with the process and help out too.
