Hi,
I'm no pro, but have done 2 weddings with the xe1. Always with primes. A black rapid rs4 over my left shoulder, and my camera bag over the right. The bag has the second xe1 body with the 35, the sling strap with xe1 and 56. I also keep the 27 in the bag for when I need it.
My first wedding shot in Poland for my friend,http://dkreativ.pixieset.com/krisandiwona/ was shot entirely with manual focus lenses. Helios 44m, 58mm f2, Carl Zeiss flektogon 35mm f2.4, and Zeiss Jena 135mm f3.5.
The second one I decided to invest as the couple decided to pay some money, prior to wedding so bought another xe1 body, nissin flash and the Fuji lenses 35/56/27. Link to shots

I've since then got rid of all the Fuji AF lenses as I enjoy shooting with just adapted MF lenses. Personal preference.
If I had another wedding coming up, I'd get another xe1 body, similar setup, but without the AF lenses. I found myself spending more time tuning focus which led me to miss shots. Also MF the xf lenses is too quirky. But this is personal preference.
I'd say the more comfortable you are carrying gear on your shoulders, better your chances are capturing the moment. Lighter gear is more flexibility. And primes work better for me. If all fails, and you have to use a zoom, and if budget is a concern. 4 spare batteries, and the 18-55 is the way to go.
Best of luck, and do share your shots.
Regards
Anand
