We figured to apply a thin coat of hydraulic cement to those areas, but one plaster company I talked to said it wasn't necessary, that their 3/16" final coat would be sufficient. Does that sound right or should we go ahead and make a hard, smooth surface below the plaster coat? Thanks

Make sure you wear the proper protective gear when sandblasting because wow it can hurt, and the dust debri also is a hassle if you inhale it, it can be fatal later. Where those worn plaster spots are, just pour reguar portland cement mixed with some sand and then roughen it up a bit with a brush or sponge. I recommen filling it before plastering because if you fill it the day of the plaster with regular plaster you may see what i call moisture spots under water and look a bit blotchy the reason being is the plaster material is not ment to go on so thick so moisture is still trapped underneath
