In case any interested party runs across this in the future .... Received the pcb's & parts, got a prototype board together and tested. The first iteration was using 1K resistors on the AC Line side (R1A & R2A) and failed the finger test (man, were they toasty). Subsequently tried 1.5K, 2K, 2.7K and wound up using 3k. The board seems to be working as designed and ran a 24hr. test with no problems. Attached are the updated schematic and pcb picture, hopefully I can put this one to bed.
