1) What are the best settings in Slic3r for printing these parts in PLA and getting good holes (particularly nut/motor shaft inserts) and part strength?
there are no universal Slic3r setting that will get the dimensions right on your machine, you will have to find that out yourself
The IMHO most important settings:
Slic3r, filament settings, filament,
diameter - measure you filament (do this every time you change filament, can vary a lot)
Slic3r, filament settings, filament,
extrusion multiplier - do a single wall test (you can stop the print when hight enough to measure the sides) slice the model, take a look at the g-code file and search for this line:
"perimeters extrusion width = 0.50mm" will normally be the same as nozzle diameter, the 0.50mm is what your single wall is supposed to measure, use the measurement to adjust your extrusion multiplier, e.g. if you get a wall thickness of 0.60, then set your extrusion multiplier to 0.50/0.60 = 0.83

This setting will also influence the dimensions, Slic3r, print settings, layers and perimeters,
external perimeters first, I do have this box un-ticked but read what Ian RepRapPro has to say about it:

About strength of the printed part, the temperature, I would not go below 185C, vertical shells no less than 2, horizontal shells, my normal setting, bottom 3, top vary, depending of the infill settings, a low setting in infill will require a higher number of top layers to get a perfect surface as the first top layer will be bridging and sag a bit - infill, 20-25% should be enough for most models
..and someone else will ad up to what I forgot
