You should clear it unless you're careless or do something really stupid.
The unrelated side note is, as its name suggest, unrelated to what you are asking though. But yes, Norse God skills are pretty useful. But the emergence of the ultimate-evolved starters generally place them low on my want list right now.
Lilith is not really necessary for high level play. Her poison is useful for quite a few dungeons though. You should get one, but I won't really place her high on the priority list.
