A few things I would change (if it match with your idea)
Will 2 : I think it's a bit low for character concept but you probably have a rp idea that come with it.
Gear :
I would encourage a lvl 4 sin with a couple of licences (easier to find information in security area if you feel safe)
Reduce weapon cost, with a low life style you probably buy ammo only when needed for example (and it's easy to find, especially for a social character and even more with a specialized contact)
What about a commlink, os and softwares ?
And glasses, ear-buds, ar gloves etc. with useful enhancement like night vision.
A medium lifestyle come with free everyday life gear and clothes and it really can make the difference for social characters who need to dive in middle class people. And your expensive car have less chance to disappear

.
Hardliner gloves are really nice for your close combat style (fo/2+1P) for only 100 nuyens and look like simple gloves. (5P damage without obvious weapon is nice

)
I prefer a lvl 1 bioware synaptic booster than wired reflexes lvl 2. No problem with cyberware detectors

but it's a hard choice. If you go this way you can use drugs or edge when needed.
I would increase perception (or int but no more points available ^_^) because I think it's more important than dodge for example (you'll use dodge only in full defence against ranged weapon but if you manage to use your infiltration skills and spot enemy before he does...)
You can learn 2 manoeuvres with martial art, check that, you may find something interesting (it need time and teacher to learn that in game and I think it match your concept)
For contacts, if you don't have written story with them I suggest a fake sin dealer or a street doctor to replace the Johnson, you already have a fixer.
For knowledge skills, a security system skill would be great (useful with infiltration and tech skill groups). And why not a firearms knowledge skill if you like customised firearms.
You will probably find bad traits that match your character to gain a few points, nice "story makers" traits in synergy with amnesia for example.
I like skills oriented characters so I wish you good runs
