Base Character: I"m not sure if Computer Hacking is legit for this campaign. Computer Programming (AI) definitely is not though, since we don't have real AI yet. Also not sure if you can count younger siblings as dependents, but I guess that's a Krys question.
Powers: In general, don't be afraid to slap power modifiers on your superhuman abilities. Super/Psionic is the most likely, and it represents vulnerability to "anti-powers" and weird science power blockers.
You can't stack DR and DR (Tough Skin) like that. Pick one or the other. Just for the record: You're basically invulnerable to assault rifles (and anything smaller) right now. Sniper rifles and explosives can skill kill you.
I'd try to jump up to ST 36 (or lifting ST 36), which is the suggested number for people looking to hoist small cars over their heads.
