Tire stores and nice wheels

Ok, so I dread having to take my 04 EX V6 6-speed to the tire place
for rotation/balance when that is necessary.  They always find a way
to f*** things up, either the interior or the wheels.  I can rotate
myself but not balance, obviously.

Is there a plastic insert in their lugnut driver to prevent the
lugnuts of my nice wheels from getting chewed up?  Can balance weights
be put only on the inside of the wheels?  Hmmmm, do the low profile
tires have a tendancy to not get out of balance as easily?

TIA
