Stuck in the West Wing

I have no idea what to do. I have gotten all the pieces but I have some items that are greyed out in my item list. I have no cheese to give to the mouse and I don't know where to get it. I have no ink to go with the pen and no bulb to place in the lamp. I have all the other misplaced items but no where to put them. Can anyone help me?

I am stuck in the West Wing also. I have collected all the pieces I can but some are locked. I cannot get the cheese for the mouse. I cannot get the ink for the pen nor the bulb for the lamp either. Please help!
