I ended up going with the comfort control cellulose. It was $4 per bag versus the $6.50 for greenfiber. The bags contained the same amount of cellulose. This worked for me mainly I think because the comfort control cellulose is manufactured pretty close to where I live. I'm sure the greenfiber is shipped from who knows where.

I'm not sure exactly what you need to do about having cellulose close to the chimney. I would look into using rockwool insulation close to it as that stuff can take massive amounts of heat. Then just blow the cellulose up against that. That would be a better alternative than creating some sort of metal dam around the chimney. Sealing is also very important, but I'm not sure what sealants are used for higher temperature applications such as a chimney. The chimney in my attic is not used anymore so I didn't have to worry about any of that.
