You can get a bolt of heavy plastic sheathing from Home Depot for under $10 US. One layer isn't quite enough so you need to double it up. Get a sheet of styrofoam insulation, cut it to snugly fit the window, glue the plastic to the styrofoam leaving about 6" overlap on all 4 sides. Put it in the window, tape the overlap to the sill with duct tape.
For the door get some self stick weatherstripping and line the jamb. a draft "snake" on the bottom works well as does a piece of old carpet. If that's not enough hang a curtain rod (metal u-shaped ones) and use a heavy curtain that goes to the floor. Remove the snake and curtain when not a darkroom.
