The settings seem pretty OK to me. You can increase the filament diameter a little (1.78 for example) to extrude a little less.

The problem with the top layers is that the slicer does slow down the speed when a layers takes less than 60 seconds, but never slower than 10 mm/s. Try printing at 190 degrees. You may need to slow down the infill speed from 60 mm/s to something like 40-50 mm/s at that temp though.

Do you have a cooling fan that blows on the printed object (not the one that cools the heatbreak)? With PLA you will most likely need it.
