Congratulations on getting married!!
As far as dance-able songs, I think her most dancy song is Moi... Lolita, but that might not be suitable for a wedding, haha. Gourmandises is also very easy to dance to, so that might be an option to consider.
Definitely consider Eden, Eden if you need a song for a slow dance! That song is great. Lui ou Toi as well.
