Sensor Dust:  I never gave much thought to sensor dust, however, the other day I did a test and found 22 spots on one body and 19 spots on the other.  Set your camera to aperture priority, 100 ISO, f-11 and shoot a picture of a plain white wall with a 50 mm lens.  Either enlarge on your camera screen and scroll through looking for spots or import to Lightroom and in the develop module use the visualize spots mode and count the spots.  I bought a batch of cleaning swabs, brand name VSGO, on Amazon for $20.00, they come in APS-C size and FF and after gently wiping the sensor once in each direction, virtually all dust spots were gone leaving only 2 and 4 respectively, good enough for me.  Will repeat the rest from time to time.
