    I've got a blog for beginners who want to learn how to control their DSLRs.
    It's only been going a month or so. I don't have anything on ISO yet, but a few posts on shutter speed already that you might find helpful. You can check them out here if you are interested.
    (Start at the bottom and work up.)

    Keep the ISO (I thought it was ASA with Canon?) as low as possible. This will reduce noise. Keep shutter speed as high as possible. This will reduce camera shake and blurriness. Keep them that way as much as possible so that you can get a good exposure, dont sacrifice a good exposure so you can have low ISO, though. Fast shutter speed is a little more important than having a low ISO because you can somewhat get rid of noise, but theres no way to get rid of bad camera shake.

    ASA is film, ISO is digital.

    Yeah, it's not a canon thing its a format thing. Film or digital.

    Set the highest ISO that you feel comfortable w/o giving you too much (or just minimal) grain/noise. 400 on most cameras is reasonable enough. Newer cameras, I'm not very familiar with your camera, you can go to 3200 and spend time looking for noise on a well lit image and probably won't find any.
    Set you flash, either built-in or external to TTL.
    Shutter - for everyday stuff (portraits to moving cars) b/n 1/60sec to 1/200.
    Aperture - adjust it accordingly to get the exposure you're looking for.

    Now the fun part:
    If you want shallow DoF, open the aperture as far as you can but boost up the shutter speed to obtain correct exposure.
    If you want to get the smoke from a candle, then slow the shutter speed but close the aperture.
    Flash - at first get a hang on when it is in TTL (either built-in or external). Ideally it'll adjust to your settings and will not let you mess up to much. Eventually, if you're shooting with an external flash - set it to 1/4power and continue adjust your aperture.

    Few things to lookout for.
    Sync Speed
    Unless you know what you're doing, try not to shoot with flash above the cameras sync speed. You'll get an effect that you might not necessarily desire. Outdoor portraits or landscape you might get away with it but indoors you might not.
    White Balance: you might get away outdoors on a nice sunny day with auto white balance, but indoors, or in shade, in the cloud, camera might get a funny reading. THEREFORE, ideally manual preset it for what you're shooting and enjoy the shoot. If you're shooting with the flash, try presets (sunny or flash or variation in b/n).
    If you got more Qs, ask away.

    ASA is an old term

    it changed to ISO many years ago.

    I shoot with the D90. This is shot at ISO-3200 with extremely noticeable noise.

    This was shot at ISO200 without noise.
