Ok here's the thing UnseenShade.

You have to take the Alchemists' Kit As is. You cant pick and choose what you do or dont want in it, other wise you'd just pick each item individually. So you can either take the entire kit as is, which includes the cost and weight of the torches, or you can just list every item individually and figure out the weight/cost of each item.

Do that, and your character is ready to go.
