One of Vairesh's hair meshes would work. (I think it's called Beth, but I can't remember for sure.) You might be able to play with hmann's Cleopatra Power hair as well. There's plenty of bow and arrow models out there, some for sale (such as Daz3d) and some for free (I believe Runtime DNA has some.) Look through free stuff for knives. willjm has a lot of great weapons - probably one of his knives would work.
