If you take a quick look in this housing section of the forum you will find the answers to most of your questions. A lot of people will recommend FN's (ferret nation cages)...

I don't recommend a c&c cage for a chinchilla, they're way too active and chins are incredible chewers for those types of cages. Also, they just don't look sturdy enough to hold ledges, wheel, etc.
I noticed you are interested in hedgies as well. It's not recommended to house them in the same room as they both have opposite needs as far as temps are concerned. Hedges need warm temps and chins need cool temps or they can overheat.
