Strength 2 is passable. Strength 1 may piss off your GM. Edge depends on your GM, one of mine used to allow it to refresh once an hour.
If you don't want to keep your Pistols skill, I suggest looking at Automatics. Get yourself a silenced Assault Rifle, set it to Full Auto, and load up on SnS/Gel Rounds/Whatever. All you do is lay down Suppressive Fire. It uses 20 rounds, it's a complex action, and it's a neat way to contribute without making yourself a great big mana-casting target.
If you'd like, you can even get Heavy Weapons (with Automatics or without). Use a Smartlinked Grenade Launcher with an Airburst Link. It can get pricey but you'll be a flexible member of the team. My last Mage had 2 in Automatics and 1 in Heavy Weapons, and he just lobbed smoke or gas grenades when necessary and lay down suppressing fire with SnS to cover retreats. Didn't kill anyone, but corpsec kept their heads down.
Oh, and you don't need a point in Pilot Ground Craft to drive. As long as you don't want to do combat in one, you can just use it to get to places.
You'll need Restricted Gear for the R4 Power Focus. It's worth it though, but I tend not to bother with it. I usually don't have a problem with casting or affecting my target, it's the drain.
That's why I would like to introduce to you the concept of Fetishes. I am in no way being bribed by several talismongers. Ahem.
You don't want your most common-use spells to be Limited, that is they'd require a fetish in physical contact to you for you to cast them. A limited Heal spell would suck, especially if a fetish is in physical contact on pieces of yourself if you get my meaning.
Fireball and Lightning Bolt... these spells deserve Fetishes. They're not "common use" spells, and the high drain will wear you out when you do want to use them. Once you get more spells, consider making them Limited if:
1) You can live without casting that spell
2) You'd like to continuously cast that spell when the situation arises
I am also not being bribed to inform you that they cost only several hundred nuyen a piece and can be otherwise ordinary looking: rings, earrings, anklets, bracelets, all sorts of tiny jewelry to more... stereotypical ones.
