once you have mastered moving squirrels try doing the same with the housing on, and then you ready to move to the have a friend anchor the picture as a "Coral Head/Sponge/Ledge/..." challenge, as a picture of a critter in the open is less interesting than of one where they are in their natural surrounding.
There are lots of good articles about the rule of thirds that do a much better description than I ever can but I will say something controversial, your camera is good enough that cropping is a good option (ie, don't zoom in so close that it fills the frame rather give it some space, this way you can crop and still have great shot otherwise you risk missing part of the critter if it moves (in my case often the head or tail) so I now try to give it a 2" buffer in excess of that I want in the picture)
