Let me start by saying, I'm not a roofer. I have built a few custom dog houses/play houses though, and have applied 3 tab or shake shingles to them all, and have helped on a shake roofing job. I've only used roofing felt under shake shingles. It is put on so the next row overlaps on top of the previous row, and roofs have minimum pitches so the water runs down, and doesn't sit there... I'll let you make up your mind from here.
