Yes, I always connect the center pin green ground lead to the metal case, 
along with the DC ground connections.

It's probably a good idea to ground the transformer case also, but 
sometimes not as easy to do and not necessary.  If you don't ahd have hum 
problems, then try it and see if it gets rid of the hum.
