Hi,

there are 5 broadhead arrows in the room where you find Norja the axe.
There's also a skull on level 7 as well as on level 8.

More to the point, given limits on carrying capacity, controlled item stashing pays off. At the end of each level, make a stash of goods near the stairs with everything you don't think is worth carrying to the next level. I typically strip each level completely bare except for stuff that has to stay on pressure plates and almost-dead torches in holders.
