My advise to you would be plan this out thoroughly, and take your time. I think you have the right idea going here, and it makes a lot of sense. I would make sure that you rehearse it, put post its on candles where each ingredient/products would go. But I think you are ahead of the game with that. But I would just rehearse it out without lighting candles, and see if it makes sense.
As for the helper candles, I mean if you feel like you can go without them then do so, but they cannot hurt to do them sense you have the main break up vigil going. You can always light a vigil light for the reconciliation and the break up to keep heat on the situation even after the spell work is finished.
