48 points is A LOT of BP to put into contacts. I can understand the loyalty rating for the twin sister and her husband, but last time I checked, unless they're really high up on the corporate chain, they are never going to have a connection rating of 6, and just calling them after a successful run against their corp can risk their job and lifestyle. So having a connection rating of 2-3 would be more appropriate.
But also considering that your troll has a charisma of 1... and no influence skills I don't see a brash unempathetic troll gaining a weapons dealer and club owner as best buddies for life, but thats just me. I think a Loyalty1/Connection6 Infobroker and Fixer can get you better results in-game and roleplaywise considering it will be just a 'business only' relationship.
Taking just that, you get 15ish BP back to but into gear, giving you 45,000 nuyen worth of more gear.
Also going to the qualities, I agree with Joush on Natural Hardening, did you think it gave you hardened troll armor or something? Because honestly thats what I thought when I first saw it in the character generators, so it's no biggie.
Toughness is only a useful quality if you've maxed out your body and still want more damage redux, or if you capped your stats at 200bp, which by your math at the bottom you didn't, so you might as well dump the quality and buy one more point in body.
Security design under active skills should be in knowledge skills.
But judging over it all generally, if you wanted to be an average stats skill monkey, it would've been better if you just went a mundane human with muscle augmentation and save yourself 15ish BP on the metatype.
