Well, Take it all. You can never have enough backup gear in case something fails. It happens and wedding/event shooting is hard on gear. Things break and you don't have the same time to 'baby' your gear as you would when just shooting for fun. If you looked at my kit, you'd think I was crazy. Every lens has a backup mate, I shoot with 2 cameras but carry 3, I have 6 flash units etc etc. There is nothing worse than when a most needed lens, camera or flash is having an issue when you have no time.

I would have both bodies set up, One with the DA50-200 and the other with the 16-50mm. The 70 mm will be used (if time permits) for portraits and more artistic shooting. But good zooms are invaluable. If you want to get into this seriously, you will want to add a DA*50-135mm or either the Sigma (my favourite) or Tamron 70-200mm f2.8 zoom to the kit. The DA50-200mm is fine in good light but frankly doesn't cut it for both IQ and speed inside a reception or church. The 10-17 will get very limited use but can take a few good creative inside shots as well as the 14mm. The 35mm will be good in some situations.

I'm saying take it all and I mean have a bag with the spare gear locked in the car trunk. Keep the 'working' kit to a minimum. 2 cameras and 2 lenses should cover almost everything you need. I would suggest you consider an FA50mm f1.4 as well. It's nice to have a good fast lens in the church were you can take natural light images and prevent having to shoot flash shots all the time. I try as much as possible to not use the flash so as not to be a constant bother for the service. The photographer should be part of the group and not stand out any more than necessary. The 50mm can get you far enough away and fast enough to shoot indoors with good results. Plus it focuses fast.
