Lou,
Yes, deffinitly DO NOT allow the silkscreen to get on any solderable pad.  It 
will degrade the solder joint to the point that it becomes unsolderable and 
you spent most of your time reworking the boards to clean the joint.  Adjust 
your stencil to take into account your vendors manufacturing tolerances, and 
maybe a bit more for bleeding of the screen.
