Black surfaces: You may have surfaces with more than three sides where the first three vertices form an acute angle. These three vertices are used to calculate the normal so you can either triangulate the surface or rotate the vertices with Surface->Change-vertex-order. That should fix it.

Booleans require very clean shapes (i.e. fully closed, with all normals facing out) and any 'faults' in an object will probably cause problems.
