If you refer to the other question/answer for your stat priority, I will cover the issue of survivability on Demon Hunters. The other question contains answers with a level of detail that doesn't need duplicating here.
Here is a disclaimer: This is the way I do it and prefer to do it, I have heard others building an effective 'tank' build for a Demon Hunter that will allow you to survive a few hits but my personal preference is glass cannon with maximum DPS and a reliance on my own awareness to avoid damage.
Survivability is managed with abilities and awareness on a Demon Hunter, you will want a certain amount of health so that you don't get one shot - I personally keep mine 'around' 30k for doing the later acts in Inferno but you can get away with lower depending on your ability to kite enemies.
Survivability comes in the form of abilities like Smokescreen (a complete immunity) which I prefer to use alongside Lingering Fog (for the increased duration), Vault (a rapid movement ability) which I prefer to use with the Tumble rune (to allow multiple uses while effectively managing Discipline) and some form of slow. This can take the form of Caltrops or one of your other abilities with the required rune to add a slowing effect.
Another useful ability is Preparation, as this restores your Discipline pool. I personally use the Battle Scars rune for the additional healing as well.
Your play-style will then essentially consist of avoiding attacks as much as possible, and any situation where you're about to take damage would result in you using Smokescreen to give you the time to get out of the range of your attacker.
