Sadly, ranged sneak attacks aren't your best option. They require you to be within 30 feet of the target and deny dex bonus to AC for the target.

This really puts you in hurt range, most mobs can walk up and smack you, the few that can't can still charge. Strongest and most reliable method for sneak attacks on ranged weapons is to play it sniper style, insane hide checks. Though playing to binary tricks leaves you either untouchable or helpless depending on what happens, no real middle ground.
