Just saw the promo. The Narn woman is Caitlin Brown (Na'Toth). What is
in the promo is taken almost entirely from the first two episodes, with just a
smidge from #3. Which may give you some indication of how much action is *in*
the first couple episodes (and in many epiosodes thereafter)
-- definitely keeping the thing moving.

I'd say that n'grath would count as a non-humanoid alien, yes? (Just
keeping an eye on my promises here....)
