I looks like both were caused by rubbing on the sharp edge of the hole in the inner rim. I had pumped my tires up to 120 lbs which is my usual pressure but it obviously caused the tube to press against the edge of the hole enough to cut it. I'm going with the tape around the hole and try the method of screwing the retainer nut on first before installing the tub. Sounds like a great solution. Thanks!!
