The blue sticky stuff is  a substitute for the missing anti-squeal shims. 
It's purpose is the same, and you can leave it there.
As far as checking the master cylinder for proper operation and no binding
of the brakes,  I would not drain out the fluid -- you'll just have to
bleed the system again.  Just jack up the car and check to see if the wheel
turns freely with the brakes off.  A slight drag is normal, since the
caliper pistons do not have any kind of positive return mechanism, such as
a spring.
