For a deeper shine I would just add more coats of the wax and nothing else. This won't last for months but it will look stunning for after the wedding. When I use the Poorboy's Wax I try to make sure that I apply it nice and thin (by lightly working the pad in a circle in the jar). I also remove it after I complete 1 - 3 panels. Then use the quick detailer you mentioned to clean it up on Sunday and it should be fantastic.
Congratulations on the wedding!
