Exact NAS make and model please chief, it makes a big difference (vendors like to use lots of odd slightly non-standard disk setups unfortunately). How big are the disks? Your best bet is to immediately remove them from the NAS and worry about that later, presuming the data is what matters. Connect them to a Linux machine to proceed - if in doubt use the systemrescuecd as your recovery environment as it comes with a vast swathe of filesystem and storage drivers that will more than likely be sufficient. You will more than likely find that simply attaching both disks and booting to systemrescuecd or any suitably tooled up Linux distro will be sufficient for the environment to automatically detect the RAID setup, optionally fsck any damage and recover the array. Report back for further help as needed, I've dealt with more than a couple of failed NAS boxes before.
