First thing I'd try is temporarily get rid of mdadm.conf. You don't actually need it. Then do "mdadm --stop /dev/md0" followed by "mdadm --assemble --scan". That'll tell mdadm to do a "best effort" to get everything running. *Always* do an mdadm --stop between every attempt, because the quickest way to mess up recovery attempts is to have the wreckage of a previous attempt lying around. If that doesn't work, then try assembling the array explicitly, ie listing all the drives. I can't remember whether order is important - so long as you don't specify --force it'll either work or fail, it won't do any damage. Beyond this point I'm getting out of my depth, I don't have the broad experience so I'll have to step back and let others chime in, but there's a good chance this will get your array back.
