I'm still reading through it all, but I honestly don't remember much undead (besides Vamps in part 5 I think). I might advice adding some back in if thats the case. I kind of get the impression after part 2 that it is mostly to highlight the Witch, (which is a little disappointing if true). Anyway, what I mean is, if your group wants to focus on undead, (in the sense that that what they built their characters for, it may be a wise idea to tailor the AP back along those lines, rather than possibly disappoint them past the midpoint? This is one of the few times that some classes really shine.
Also, just a warning, the moral decision in part 5 might just be a little too stretched with both a Cleric of Pharisma and a Paladin (Undead Slayer and of Imodae. . .), depending on your style of play.
My group has a cleric of Pharasma, and knowing about the moral choice in part 5, I had a chat with the player about moral choices and how he would have his PC act if confronted with one. We talked a bit, and we came to an understanding that sometimes, you have to let the small bad live, so you can kill the big bad. Of course, you can always go back and kill the small bad after the big bad is dealt with. :)
