Crystal Healing

I wanted to ask if anyone knew what the guide for a thurifer in a wedding is. Here's what I know:

1)Process up the aisle, in front of the crucifix.
2)Let the priest incense the altar and people etc
3)Hang out until the Gospel
4)Let the priest do his incensing and stand behind him during the Gospel
5)Sacrament of Marriage...hang out.
6)Once the Eucharist stuff starts up, the priest needs thurible before he washes his hands.
7)During the consecration kneel at the foot of the altar and cense in sets of (2-2-2).
8)Process out.

Please, only answers relevant to the question. Save anything about how God is fake or how the Catholic Church is evil or molests boys 24/7 for another topic.
Only because people will come up with unoriginal remarks and jokes about the sex abuse scandal. I just wanted to avoid it.
