My Obstetrician used staples. Although the thought of staples terrified me I have to say that they were brilliant. I had them removed (I had 19 of them) 4 days post OP then a steristrip was placed over the scar which I kept on for about 10 days. It didn't hurt one little bit when the staples were being removed. You can barely see my scar and there are no little dots where the staples went in either.

Re: the overhang. It's not usually your scar that causes this. Moreso just the fact that your skin is stretched whilst your pregnant and of course if your a little bit bigger you have more chance of an overhang. I call it a stoodgy belly! Also some people are just more prone to it then others . . .
