Loading Maps
From the console, use the following commands:
map e3/intro (Loads Intro Movie)
map e3/e3_1 (Loads 1st Map)
map e3/e3_2 (Loads 2nd Map)
map e3/e3_3 (Loads 3rd Map)
map fred/e3bathroom5 (Doesn't Work For Most People)
Controls And Settings
In the console, type: bindlist
This will list all the currently bound keys and their functions. Use the page up and page down keys to scroll through the list. As long as you deleted the doomconfig.cfg before you started up, your settings should be pretty good.
To change any of these settings, you can either type in different values from the console, or just manually change the doomconfig.cfg with a text editor.
Popular Commands

In the console, type: com_drawfps 1

Invert Mouse:
m_pitch -0.022
The default setting is m_pitch 0.022, all you need to do is add the negative sign.
Third Person view:
pm_thirdperson 1 (Third Person ON)
pm_thirdperson 0 (Third Person OFF)
Recording Demos
bind F5 recordDemo (Start Recording)
bind F6 stoprecording (Stop Recording)
These two binds will give you keys for starting and stopping a demo, respectively. You can substitute in the keys you prefer, it doesn't matter. In this case, when you want to start capturing the action in the game, press F5. When you're done, press F6.
The demo files are stored in your Doom_III\base\demos folder. They will be labelled incrementally, e.g. Demo001.demo, demo002.demo, etc. To play back your demo within the game, type playdemo demo001 (or whatever the demo filename happens to be).
However, to get your demo into a movie format, there's a few extra steps.
Making A Demo Into An AVI
After you've got a good demo, type aviDemo (for example, aviDemo demo001).
This will play back your demo while taking a whole bunch of screenshots. When it's done, exit the game and look in your "Doom_III\base\demos\demoname" folder. Depending upon how long your demo was, you could have anywhere from 100mb to 10 gigs of .tga files.
Download this program and run it:
http://www.css.tayloru.edu/~btoll/f99/350/res/pjBmp2Avi.zip
From the program's main screen, in the Directory field, type in the path to your demo's screenshots folder. (The "Doom_III\base\demos\demoname" I described above). A quicker way is to click the "..." button and just browse to the directory.
Change the file option from BMP to TGA. You should then see a list of all the screenshots appear in the "Files" field.
Under "Output" options, type the path and name of the avi you wish to create (e.g., "C:\movies\doom3rocks.avi")
Leave the default Frame and Key Rates (if any of you movie experts suggest a better setting, let me know).
Click the create button. A new window will pop up, prompting you to select a video codec. I suggest you use Divx 5.0.2. After you click OK, the program will compile your .tga files together.
After the window closes, you're done! Go to the target directory you specified, and watch your first Doom 3 movie =)
Cheats / Hints
In the console, type:
God Mode: God
Extra Health: Give Health
Weapons: Give Weapon_x (e.g. Rocket Launcher, Plasmagun... although some of these will crash the game)
Fly Through Walls: Noclip
The keycode for the pad in Level 2 is "924"

Closing The Game, The Right Way
Whilst in-game, look down at the floor to boost your framerate. This will release the stress on the graphics card/processor, therefore speeding up quit time. Then open up the console, and type Disconnect. This will remove the map/weapons etc from the computer. It will take upto 10 seconds to finish. Finally, type Quit. This will remove the game engine from the computer
