With my shears, no.  Results may differ with different shears, different 
thicknesses of board, etcetera.  Best way to test is to do what I did - 
take a piece of board to the shop and get them to let you try it out.

Sorry, can't help you there - everything I do is one-off, every board 
pre-cut before I expose them.  I wouldn't anticipate issues if there is 
no copper on or close to the line of cut though.

Cheers
