I think most root templates can attack with their fists unarmed.
Are you using the ImpPlayer root template for the PC? Or just a random Imp?
Also for stats/equipment issues usually restarting the editor after you set all the fields will do the trick. But you can also just reload the story for global characters.
Have you tried just placing a weapon on the ground to pick up and use for now?
Most of these issues are probably due to how character creation works. It's probably trying to give your imp a weapon it can't use. You can disable that by simply commenting out Player1 from being added to character creation in the story editor.
