The swabbing procedure is not hard, maybe it's scary the first time or two but the results are worth the effort. Offset the cost of the swabs against the time wasted repairing dust spots ...
Lens changing. Do it in a clean environment if at all possible. Keeping the mouth of the camera pointed downwards seems to help.
OK, you may need to stop down to get depth of field, but small apertures risk deterioration of image quality due to diffraction effects ... f/8 is small enough for most lenses and with the better ones there's little if any benefit from stopping down below f/5.6. Use the biggest aperture you can get away with, the effects of small dust specks (a few are inevitable) will be far less noticeable & for most images you probably won't need to patch the image at all unless the sensor is really mucky. Also, when stopped well down, dust on the rear element of the lens can become an issue.
