Maybe the label_outer() function will be what you need. Call it for each
subplot axes, and set the labels as you would normally. matplotlib would
then set visible only the labels that are on the outside edge.
Another option is to use the AxesGrid1 toolkit, which makes these things
easy. Also note that the soon-to-be released v1.1 will have a
tight_layout() function that can help with your spacing issues.
Cheers!
