Unity 2d Animation Question

I have a character exported in a .PSB file with layers for each part, Unity pulls it in perfectly, but the character has some extras like a gun, a rifle and a second head where he is grimacing. When I go into the editor I would like to only use certain pieces for specific animations, however it looks like I have to put the character together in Photoshop so everything is lined up and then pull the character in. Am is missing something?, I would like to unity to have the extra pieces and then...
