Him and his friends should be near the houses right across the street from the pub.

I'm assuming you've already met Cobb in the Saloon. Joe Cobb hangs around the southern end of Goodsprings, on the road to Primm. He can be seen leaning against an old house, usually the one visibile from the "Speed Limit: 50" sign on the road.
Here's a screensnap if you think it will help, that's him over there; I know the visibility is "Eh" but I resized the shot from the huge 1920x1080.
