How to make an array of holes?

 From:  nycL45
A two-parter:
1/ I am modeling a kitchen tool, a long handled shallow bowl-shaped strainer, and it has lots of holes (1/16"/1.5mm dia., 1/4"/6mm o.c.). There is a center hole surrounded by a hexagonal group (6) and then hexagonal-based concentric rings of holes thereafter with a wedge of holes in the left over spaces. Of course these holes follow the surface of the shallow bowl. How do I go about creating an array of booles and then mass-boole based on this hole pattern in MoI3D?

2/ These holes, on the handle side, have eased (convexed) edges. So, whatever is used to boole the holes, should flair out to ease the edges. Does that sound right?
