Aura of Dark Majest + Beguille is a great combo. It makes it harder to get hits on your vampire which makes them far more survivable. I like this alongside the power that gives you +2 WS. High WS makes that combo even better. The sooner you can make them fail on their attacks, the better. Plus Aura is helpful in general as well.
Quickblood is a very solid choice, I never leave the lair without at least giving it to my Lord and maybe the hero as well.
I currently give the Ogre blade to my Lord. High strength, without having ASL? Yes, please. It tears up monsters, characters, chariots, etc. Against knights it carves through armor with easy. The only time it really doesn't make a difference is T3 rank and file (elves usually can get decent saves on their characters, so it helps against their characters). However, if my lord is striking RaF than he probably has no other targets.
While Red Blood is *very* nice, I find it hard to take. There are a lot of other powers I really like, mainly because I want some general support powers from him (Aura of Dark Majesty being a primary one, and even fear incarnate). I figure that if I tool him up right, he can kill a character on the first go. Plus if I give him proper support to the unit a couple extra kills on the unit won't be so critical.

Extra hand weapon
The extra hand weapon on her gives enough attacks to be a threat to all, plus she should be tough to hit. So she can swing away regularly. I am nervous of her not having ASF, but it should work.
