Quickdraw and two weapon fighting let's you throw daggers at range when you win initiative and they're still flat footed, or when a wizard casts grease on them or whatever and also melee it up by flanking afterwards.

Also, if playing 3.5 (this doesn't work in PF) and if your DM allows it (some don't) you can do ranged touch sneak attacks with Alchemists' Fires, Acid Flasks, Holy Water, etc. (more applicable in higher levels after you can get a handy haversack or something, can afford to carry many of them and/or can convince a spellcaster buddy to craft them for you (or craft them yourself if your DM allows you to (many do) ) but they might still come in handy in early levels).
