Well, tougher for you; I know all the answers already because I wrote the puzzle. These are all things I could answer without consulting reference material or the Internet.
If you can finish the puzzle without any help, then you are as big of a freak as I am. But don't feel bad if you have to look something up. That just means you have a life and are probably well-adjusted socially.
Special thanks to pal Jessica, who made me aware of the program I used to make this puzzle, which you can get here.
