Well, the spool directory is inside the $SGE_ROOT/default/spool, but the best way for me is in the middle: to export $SGE_ROOT to all machines, while redirecting the spool directory to a location like /var/spool/sge, which needs only to be writable by the SGE admin user (the "/var/spool/sge/qmaster" needs to be created beforehand, while the spool directories for the nodes will be created automatcially when the sgeeced starts).
