Let's start with the basics:
Click here to download the freeware version of Game Maker 6.1 (you'll need the registered version for the class, but it's very inexpensive)
Click here to get to the Game Maker main web support page

Now, for some advanced information as you're working on your course project:
The Game Maker Forum is a good place to get your questions answered that I cannot easily help with (i.e., those related to the class tutorials).
Here are over 400 Mini-Tutorials concerning various things that enthusiasts have discovered Game Maker can do. Maybe what you're trying to accomplish is here? This whole site has lots of Game Maker fan support.
The Resources page also includes more than just sprites and audio files; there are also animation tools, and a game 'script' database.
