You kinda made a winner first go, if you can in any way take a better version of the power foci that'd be beneficial to you. The knowledge skills you took are going to be first rate for you though, look up Amderma on google maps, there's a reason I picked that location.
You took sensitive neural structure which means no ware for you, so that really bars you from taking any of the program's core enhancements. I understand your guy wants to remain pure, but having a sensitive structure like that would borderline bar him from employment at TriSeq, so you would have to have tried doubly hard as a mage to prove you don't need that ware to get through the program.
If you need karma from negative qualities, everyone should have (or if they don't have it will be awarded) "Records on file: TriSeq", another quality, that triseq would easily soon find out about but would not bar you from the program would be Nano Intolerance. Nano machines are used in most surgeries so the surgeons would note that your body quickly flushed the nanites whilst you were recovering from surgery.
Something else, being the upperish class person that you are, you might have Media Junky, Mild. You wanna keep up with your friends from school, peruse through wikis constantly to sate your interests, or just zone out on trids. Being so isolated this habit could easily have developed in just the last six months.
Something else, if either of you can afford the karma you could take a level of initiation, I'm sure TriSeq could have flown in a combat mage instructor to really show you how magic works in the battle field, which could justify combat spells you have. You could also take a mentor spirit, but be warned, any of the head strong mentor spirits that do not take advice or orders well would most definitely land you on wage mage guard duty until your ware and training are payed off. (IE at those wages, years) as well, TriSeq isn't a major dirty deads organization, though neither are they valiant knights, they're the PMC Version of the Spetsnaz that pays better, and they take allot of red army money to help them (The Red Army) look good or even trip up the military political competition, so honour isn't above secrecy and getting the job done.
Thinking about it, spells like slow could be beneficial to the whole team, they may not stop bullets or missiles, but they just might save you guys from a major crash, or even environmental hazards and pursuing threats if you can react in time. Improved reflexes the spell is a force multiplier, you're effectively creating a second person to output fire with that spell.
Another thing are spirits and watchers, conjure yourself some sneaky watchers to act as advance scouts or to keep an eye out for outflanking enemies. Or summon a couple spirits to help you out in combat, or act as a tail chaser for the enemy.
Stealth spells, you guys may have armour that can evade all manner of detection, but a mage with the right suspicions could blow that, investing in the ability to shield the party's astral signatures as well as physical signatures would be greatly beneficial.
Healing spells would be supplementary, as you have two highly skilled, well equipped medics (More than quadruple normal medic allocation per soldier.) but the ability to quell the effects of toxic effects could save some lives, since magic is more general utility than the specific antivenin and antidotes needed by medics.
Astral combat isn't terribly necessary as spirits could handle the defense portion of it for you. The only time you'd engage is if you astrally projected into an enemy camp, and actually breached their facilities which are usually designed to prevent you from even getting there in astral form in the first place. (Wards, being built underground, having astral barriers grown over the building or general area.)
note, I'm pretty new to magic so could be making this all up.
Another thing, please don't abuse levitate for shenanigans and munchkinry,
Edit: You could even take the ordeal discount to initiation, because hell if TriSeq would make it easy for you.
Edit Edit: I'm truly sorry if I skipped over you, or you feel left out in any way.
