To answer your immediate question about firmware, you can get blob firmware by
following the insturctions at

https://nouveau.freedesktop.org/wiki/VideoAcceleration/#firmware

to the letter. Unfortunately I think that linux 4.9 wants some of these to be
renamed, but there's a patch to fix it to look for the "old" names as well:

https://github.com/skeggsb/linux/commit/e137040e0d0376b404fc5155eba44ea07126e3bd.patch

Should be included in a later 4.9.x release.

However I'm only aware of the blob firmware fixing issues for some GTX 660
owners.

nofbaccel=1 is unlikely to be of much help - that disables acceleration of the
fbdev device for your terminals.

Note that there are additional patches in Linux 4.10-rc1+ which are likely to
improve stability, such as

https://github.com/skeggsb/linux/commit/b27add13f500469127afdf011dbcc9c649e16e54.patch

and you might also want this one, although it'll be a little annoying to apply
to upstream tree:
