I'm not 100% sure about the fanaticism, i'd have to test it.But I'm pretty sure thats how it acted when I was playing around with it.

About banish yea you can banish your own undead. And about bless I don't think you can but I haven't tried it.

Edit:
Test Results: you can't bless enemy troops even if it hits their sqare.

Thats is different from other spells like quickness, marble warriors, legions of steel that work on enemy troops as well.

I think there was something about when you enslave mind some blessed creature and the bless changes from theirs to yours but don't remember it exactly.
