I know that a DM can plan for this possibilty, and can try everything to avoid its occurrence, but it may invariably happen and throw a wrench in the story's works.
Also... Just from experience with my players, they have a tendency to kill first and ask questions later;...
I know exactly what you mean, but I can honestly tell you that the Vampire is not the only victim to these circumstances. In one of my games, there is a Knight of the Chalice. Against anything but demons, he's pretty much toast because the PrC is so very focused on doing one thing. However, when pitted against demons, he just about walks right through them. Even if I roleplay a Balor brilliantly, one that takes great pains and makes extraordinary efforts to keep the battle on his own turf, that damned KotC is a tough man to take down. When he's at full combat readiness and successfully makes but a single strike against a demon, the guy throws about ten dice on the table. Ten! Per hit!! Ugh.
Aside from "The Mosted Hated Ranger Of All Time", I've never had as much trouble as with the KotC. When dealing with this paladin, everthing comes down to tactics, a battle of wits, and believe me, the battlefield isn't restricted to actual combat. I think that's the key to Vampires as well. They are great in combat, except for the very real risk of being staked, but because of this vulnerability, they should take great pains to protect themselves. When done so properly, they can make a very formidable enemy.
I honestly think that Vampires can be portrayed one of two ways; either defensively or offensively. When portrayed defensively, they do everything they can to avoid confronting the players. Essentially, they just run and hide. When portrayed offensively, they take the battle to the players on their own turf.
That's the trouble with intelligent monsters; they're only as intelligent as the person portraying them, and I'll be the first to admit that I am certainly not an individual that has the brains nor capability of taking over the world.

...subtle coercions and slower plot developments get run roughshod by players looking for the enemy and being ready to kill anyone with the hint of badnik.
This is very true. From my own experience, this can be the biggest monkey-wrench of them all. With these types of players or this style of game, Vampires don't really make a very good foe, primarily because they are cerebral in nature. With players or a game like this, a boat-load of ogres or stupid giants is probably more appropriate.

Maybe I should run a few solid hack-n-slash days to get this out of their systems...
That just might do the trick. Let me know if it works and I might try that myself.
