Over on the house side of this 15 foot separation, the station ground 
system and electrical ground will be tied together.  At the corner of 
the house closest to the antenna SPG, I plan to extend/retract coaxes 
and control lines from the house to that antenna SPG.  So my 
QUESTION:  Should the ground wire connecting the station/house system 
to the antenna SPG also be disconnected during storms (like the coax 
and other lines)?

Not having the electrical ground and the station ground as one and 
the same violates the concept of a SPG.  However, for most of us 
tying them together with a ground wire between them is the best that 
can be done.  I used additional ground rods for this large copper 
wire connection buried in the ground.

Lightning: Understand It or Suffer the Consequences by W4QEJ in the 
February/April issues of QST is an excellent source on why having a 
SPG to protect against the higher probability of a near-field 
lightning hit works.  Also I completely agree with the comment made 
on disconnecting the antenna/radio lines - it is just not a good plan.
