You scuff up existing paint for two reasons. First, you want to get rid of any oil, grease or dirt trapped in the top layer of paint. This is the stuff that cleaners and degreasers can't get off.

Once the drywall compound/spackle has had sufficient time to dry, you will need to lightly sand the surface of the repair to smooth out any ridges that may have been caused while "coating" the patch. Once you have the surface sanded smooth, take a wet sponge or cloth and, by lightly washing/rubbing, blend the outside edge of the drywall compound/spackle back into the wall. For a smaller repair, you can wash away the excess drywall compound, leaving only the compound/spackle only in the area where the indent was filled. For a larger hole, after filling, sanding and using a wet sponge to blend the outside edge of the compound back into the wall, it may be necessary to texture the area in order to give the smooth patch the appearance of the existing wall.

Use Tinted Primer for Dark Paint Colors.In our second case, suppose you want to apply a deep, dark blue to a beige wall. The good news is that it will be easier to darken a light color than it was to lighten a dark color. In fact, it may only take 2 - 4 coats to get total color coverage in this scenario. The bad news is that if you start out with a white primer you are already moving in the wrong direction. Doing so could increase the number of paint coats you need to 3 - 6... plus the coat of primer! That's a lot of painting!
