Death Frost Doom: Let me learn from your experiences

I'm about to start a short campaign, with Do Not Let Us Die in the Dark Night of this Cold Winter followed by Death Frost Doom.

Have you run Death Frost Doom? How did it go? What levels do you recommend? There's almost no combat, but there is one pivotal potential fight -- do I want the characters to be of a level to have a credible chance of beating it? Are there changes I should make to the adventure or things I should add to it?

Thanks in advance for any help you can offer.

The only bit of Death Frost Doom I've used is the idea of an old man who is burying the neglected dead. (In my take on this he could learn the name of a dead being by touching the body - I don't think this is in the module?)

As far as the main trick in the dungeon is concerned, it seems to be borrowed from an old White Dwarf adventure called The Lichway which was for low-level PCs. That doesn't really help you though, sorry!

Not with that attitude.
