I have to admit, when I was confirmed in 7th grade, I was thrilled because, to a 13 yo, it meant that I didn't have to go to religious instructions anymore... little did I know that 2 years later, I'd be in a private Catholic HS, and then college where it was a requirement.
I remember thinking that I was so happy to be Catholic and not Jewish, at that time. The Catholic children have to learn answers to questions that the bishop may ask them. These questions are in English and you can raise your hand to answer the ones that you remembered. My knowledge of the bar/bat mitzvah was that the child had to learn all sorts of prayers in Hebrew and alot of them are sung to the congregation.... and they are alone. The thought of that would still scare me. I don't sing in public... period.
Seriously, though, the definitions that were given on the Sacrament were very good, and I'm not trying to make light of the Sacrament. I'm trying to give you, from what I remember, what a 13 yo's perspective was. Once I received Confirmation, I taught classes for it during HS. I hope I didn't offend anyone by appearing to be flippant.
Confirmation makes you a Soldier of Christ. The child selects the name of a Saint to take as their own during the ceremony and they select a sponsor to guide them through this Sacrament. Symbolically, the sponsor goes to the front of the church with the candidate and places a hand on the candidate's shoulder as the oil is applied to his/her forehead.
Again, from the 13yo's point of view, I'd have preferred money as a gift. I'd have expected my parents, grandparents and sponsor to give me something personal and religious, not anyone else. You can't go wrong with cash, and quite frankly, knowing that you are Jewish, I'd wonder why your DD would be giving me something that represented Christ since He is not a part of your religion. I'd think you were trying too hard.
As for your DD going up to the front of the church during Communion, I'd suggest that she doesn't. She will be not be noticed for remaining in her seat, but if she goes to the front, so many people will notice that she's crossed her arms and didn't receive. She'll call more attention to herself that way.
FWIW, the church will be packed for the Confirmation. When it comes time to kneel, please do it with the rest of the congregation. It doesn't mean that you are praying the same prayers, but the person kneeling behind you will be very grateful that you got out of their way so they could kneel comfortably, too, and it will keep them from breathing down your neck.
