So for the combat side your gonna need wired reflex, some reaction enhancers, a pair of cyber eyes with smartlink, maybe some muscle replacement for boosting str agi.
Your probably want some decent cash for this build so recommend a fairly high resource allocation also gonna need good stats, so dump magic.
Facing isn't to hard, you need etiquette negotiation and Con, the first impression quality if very helpful for faces, push cha so it can help you get a decent number of contacts, and the make your contact fairly varied. So you have someone to call when it time to do some leg work.
Next get some nice armor suit something that gives you social limit, Sleeping tiger i think is my favorite.
With Good suit armor anti-ballistic mask and a decent body should have you solid soak, and hight Ref+intuition is the best defense possible.
You shouldn't need much edge, I'd recommend 1 for the money roll, and then whatever you feel like you need for accidents.
Keep your skill list really simple. Unarmed, Pistols, Con, Negotiate, (All at 6 if you can, and spec them if you have the points) Etiquette, drive, sneak with a couple points is helpful.
Pay attention to derived states. JUDGE INTENT, very valuable, and COMPOSURE is just slightly less important.
It goes without saying but just to be sure, Avoid negative qualities that hurt facing.
Edit:
Oops I missed that this was 4e, most of this should still hold. Though it's been a bit.
