I can't say if it's going to help or harm to wax it now and then try and work on it later, but I suspect that wax could be washed off with waxing grease remover.
Doran says you're going to go back and send it anyways.
I have only wax the top half of my boat a couple times I don't believe I have ever waxed the bottom, here's a photo of the part of the hull that I did not wet sand and buff. I suspect that buffing it even with the orange peel would've helped the situation with the black marks from the rollers that was from the old roller trailer. Not sure if that helps with what you're thinking or not but again I would say put it in the water worry about the bottom next year.
I may never try and get those black marks off the bottom on my hull.
