Having a slower shutter speed will blur out the backround of a moving object but the image needs to be panned (camera moving with the object)

what you are talking about is depth of field. to blur out the background set the aperture to a low f number like f4

yeah it called depth of field and you can also do reverse depth of field ie background in focus foreground blured :Y:

erm that would just be achieved by selecting a different focus point.
changing the aperture on the other hand will keep the main plane of focus in the same spot but simply changes the amount the focus falls away

f/8.0 ........................................ f/5.6 .................................. f/2.8

as you can see in the example above all the images are focused in the same place (the statue face) but the focus falls away in the distance at different amounts depending upon the apperture
