I have a couple of thoughts too, on those points.

1. Balancing against Grand Thaumaturgs isn't necessarily a good idea since the main point of the GTs is reanimation. They make 4 cavalry each a turn, which is extremely powerful!

I assumed you had made grey seers expensive to restrict access to death/astral (which is quite reasonable). They are not especially better than the warlock engineers to my mind. But at the same time I have no problem with them being expensive. I would only build a very few, but they are meant to be special.

3. Again I have no strong problem with this pricing. It is annoyingly expensive, but as you say I wouldn't expect it to be trivial for Skaven to lay down Sermon of Courage. One thing though - the fact that a unit is multipurpose doesn't really make it much more valuable to my mind, since it can only do one thing at once. If I buy a plague priest to accompany an army (the only reason I would, I think), the fact that it can summon troops is largely irrelevant. Similarly with the packmaster - the fact that he can do stuff apart from summon rats is of no use to me if I recruited him to summon rats.
