It only took a few days to learn the camera inside out so that I'd feel comfortable being able to go right to the control or switch without thinking about it in a stressful situation.
I was happy I knew 'what' needed changing within a day and 'where' it was within a couple of days (without having to think about it), but as you know, when the stress kicks in all that will fly out the window. So, give it a couple of weeks and you should be all good to go. Use it for 30 mins a day between now and the wedding and you should have no trouble at all.
So basically you were completely manual? I'm assuming that you relied heavily on the Zebras to let you know if your gain and iris settings were correct?
Yes, completely manual, use the zebras for exposure. Also, be aware that the LCD can be set to different brightness levels which is toggled by a switch near the LCD. One of our guys was constantly underexposing things and I traced it to the LCD brightness setting on his camera being different to all the others. Since I don't have a camera anymore I can't direct you to the exact menu, but this toggle can be disabled in one of the menus and I absolutely recommend doing that. For real exposure control you can of course use the vector scopes but they do get in the way a little.
I think I'm going to be in 24p at 1/50 shutter speed most of the time. I really like that look...
We shot at 1080/25p (because we are PAL) and it was fine. Fast pans aren't pro anyway

Do also check out the 720/60p mode for slo-mo. With a little neat video applied (and possibly some unsharp mask) after up-res it matches with the 1080p quite well.
BTW - we also disabled the servo zoom most of the time since we cut out any zooms in post (nothings scream home movie like random zooms - right?), so we wanted zooms to be as fast as possible (so we'd have less to cut). It also helps when zooming in with the focus assist, because the power zoom would be too slow to wait for. As with AF, the only time we ever used powered zoom (and even then at the slowest setting) was for the recessional, and we stopped doing that after a while anyway.
