If I have to use screws for a box I always fill hole with glue (titebond 3) then top it off with wood filler to get that smooth feeling and look. But I try to use clamps whenever possible.

as far as cracks what do you mean cracks? splits in mdf? where there are seams? or cracks where bonds are made?
