Activity for Grace

My fiance and I don't attend a church or practice a religion. I was wondering what kinds of ceremony options would be out there that weren't uncomfortably religious for us.

So I have too many girl friends, and I don't want to hurt anyone's feelings picking a maid of honor or have them fight over a placement next to me at the altar. So I was wondering if it would be weirder to have no bridesmaids, or have my guy friends...
