Sure, that build can work. If you're willing to optimize a bit more, read on. If not, that will get you through the game ok, so have fun.
I don't understand 4 Will. Take that point and put it somewhere better. You don't even have Persuasion or Intimidate to justify the point as "penalty avoidance."
You're way overinvested in Biology, Electronics, and Mechanics. Most of the time you don't need those points, so really what matters is what you can buff up to, because mostly you'll be crafting in safe areas in "down time" rather than on the fly. I'd pull back 60-70 points out of Mech and Elec, and - depending on if you want to be able to craft Super Soldier and use the highest tier poison or not - either 40 or 60 points from Bio.
You're 25 points overinvested in Hacking for even the highest possible check in the game while carrying no buffs. I'd reclaim those points, too, and also pull 50 out of Lockpicking since you can pop every lock in the game with 80 real points and 7 Dex. You probably don't need but half that Traps skill, too. Certainly you don't need more than 100 real points.
Now you have 1 stat point and 255 to 315 skill points free. The possibilities are endless. I'd put 80 points into Tailoring and 40-50 into Chemistry because it's nice to be able to make your own traps and grenades, plus the armor you can craft will be much better than the stuff you can buy.
You should pick up Ambush. With that much stealth, Ambush is going to be extremely powerful and valuable. Take Sprint earlier. It'll save your life, because you'll occasionally need to reposition abruptly during combat, as a bowman.
You can link to your builds in the build tool by pressing the "Link" button in the options heading, on the left side of the screen midway down, then just copying and pasting the URL that comes up in your browser address bar.
EDIT: Sorry, forgot to answer your throwing question. Yes, you want some Throwing. I might only put 50 points in with 7 Dex, rather than 80, but Throwing is what will determine the precision of your caltrops, grenades, and nets. You're going to want to use all of the above, as a xbow.
SECOND EDIT: Numbers are hard and apparently I cannot read. Changed recommendation for points recovered from Mech and Elec because I thought all 3 were at 140 in the OP.
