As shadowcat says, con and/or etiquette work well. Having four dice gives you a solid chance of a hit when you need one (or you can buy one if your GM allows) with a low risk of a glitch/crit glitch given the amount of dice.
Your template is a really nice start, just could be tweaked with some optimization. You could go Resources A Attributes B too if you like a version better like that.
I'd worry less about soak (beyond your armor) but that's just me. If you have Intuition 5, Reaction 5 (9) [with wired reflexes 2 an reaction enhances 2], and Agility 7 (10) [probably with used Muscle Toner 3], and the Agile Defender quality, your regular defense pool is 14 dice, and you can get 24 if you go full defense. WIth that kind of dice, you can likely dodge even the most accurately shot weapons. With your initiative, you will likely have 3 passes, so even if you go full defense, you still have 2 passes to make attacks.
And don't forget, your character will grow! Have a wishlist for skills/gear/'ware. Starting characters are experienced shadowrunners--they should have what they need to be competent enough at what they do to get hired for a shadowrun, but they definitely are not the best in the biz yet. You don't need everything from day one, you just need to be able to hit the ground running, survive, and get paid, not necessarily in that order.
