What if my character uses a ranged weapon, such as a longbow, crossbow, shortbow, etc. and the enemy isn't aware of an incoming arrow/bolt? Do they automatically gain awareness and deflect the arrow/bolt and charge down the field while my character waits to be countered, checking the local news on his/her iPhone? What I'm asking is about ranged bow attacks and sneak attacks. How are they implemented? What are the chances of a sneak attack successful, and how does a sneak attack differ from a normal, face to face attack?

You [b]do not have to rely on the mechanics for your posts[/b], nor would I expect anyone to use them for every monster encounter. I myself will likely use them from time to time, perhaps when dealing with significant enemies or certain situations, but not allllll the time. 

That said, there'll be a little mention in the final draft of how to "combine" stats when you want to do something tricky. Basically though, it all comes down to common sense. 

So in your example, your guy has a crossbow, and he's snuck up on some unsuspecting Orc from a safe distance.

Agility vs agility, for the Orc not noticing you rising from cover to shoot your cumbersome weapon. 

Automatic wound roll would then follow, using agility (the stealth stat) to determine the effectiveness of the strike. Because the Orc isn't bracing - he hasn't seen you - and he can't fight back because he's too far away to do so. I guess because this idea of the attack may be to take him down quietly, you could make the hit an insta-kill. I'm not moderating the rolls, hell no, they're an aid to be used for the purposes of fun. 

OR

The Orc sees you. Now he know's he's in trouble. What does he do? Run at you? 

If he runs at you, you'd use your strength like you would normally. Whilst a crossbow doesn't involve much muscle mass to pull the trigger on, they're still heavy weapons and need to be kept steady. Automatic wound roll because he can't fight back - same result as sneaking up on him - except now he's real close if you haven't taken him down. 

Maybe he braces for impact? Diminishing your strike, and then sprinting at you whilst you fumble to reload? 

Picture it in your head, think about what would happen, and try to fit it loosely with the available input.
