I got this information from another forum, but I think it might help give you some ideas......
1. the person you select as an officer to oversee the event (or provided as you may not know any officers to comission you) reads you the oath. now, some locations, like the university of colorado, do a "real" comissioning with the XO and then you can have whomever you want to read you the oath for ceremonial pourposes afterwards in the auditorium.
2. Your bars are put on by family, or bars on sleeves revealed, depending on the time of year.
3. the first salute, which is normally purchased by the newly comissioned by a dollar-coin.
beyond that it's up to you. I've seen tributes to the spouse (normally for mustang ceremonies to show appriciation (sp?) to their wives for all they have endured thus far in support in their navy careers), typically a chaplin provides a prayer, and possibly a keynote speaker, followed by a "wet-down" at a local bar.
but, all that really matters is that you swear in and sign the paperwork......
