If you are shooting a wedding tomorrow, rather than ask for advice here
I suggest you go out ASAP and shoot lots and lots of test shots with all of the settings you are interested in, with all of the lenses you are planning to use for the wedding, and see how the camera works for you in hand.
Then sit down in front of Lightroom (or whatever you use) and review all your test shots to see if they came out as you expected, and get comfortable with how everything is working for you prior to shooting the wedding.
