PLEASE ANSWER FAST!!!?

I'm about to go on a haul for my Guinea Pigs. I need to know what bedding is the best. Not carefresh, though. That bedding gave my pig, Delon, resrespiratory problems. What wood shavings are the best? Also what is the best, non-pellet food? Hershey, my other guinea pig, hates those. Latsly, what are the best beneficial, healthy treats? I want to give them a little extra something. I can't give them gr because its still snowing and very cold here ( I live in the northern part of The Northwest Territories, Canada). All the info I need will be chosen as best answer!
