I went out to the book store (man, this whole post is nostalgia central - phone books, book stores) and bought "Reader's Digest Complete Do-It-Yourself" book, learned how to glue plastic pipe and parts together, and fixed it, and the drywall, myself about a week later. 

I didn’t do anything except number 4 and 5 (I left the excess garbage on the curb in plastic garbage bags) and for the light switch.
