He seems like a good mix of specialist (face) and generalist (can do other things). You can make real monsters by piling your points into your specialty, but to me, this character, similarly to the Tir Ghost NPC example, is what a true prime runner will usually look like. Not someone who could overpower a 400-BP character, but rather one who has a much greater breadth than a 400-BP character.
SR4A made some efforts to reign in "pornomancers" (amusing, since I don't know if there were ever any that were actually played), but my feelings about that are mixed. The caps on social modifiers will really only affect the extreme cases that no one would realistically play, anyways. They would have done a better job if they had given more clarification on what social skills can and cannot do. That's always been the biggest problem with social skills; GMs who treat it as mind control.
