What should I do for my guinea pigs?

Ok so I'm getting another guinea pig friend for my current guinea pig and I'm getting a c&c cage w/ coroplast and just wondering what I should do for bedding. Thinking about getting a fleece fabric but how much work is that? I mean what do you have to do??what do you do with it?? And would it be cheaper and worth it to just get bedding instead??? HELP
