Drilling through rafters or trusses is not advisable in that it greatly reduces the structural integrity of the roof and the building. Many GCs and engineers won't allow it. As far as recepts on the load side of a GFI I was always taught no more than 4 on the load side due to more of a chance of nuisance tripping. The bosses request on the stacking of wires, well he is the one who signs the check.
