I can't think of any online resources off the top of my head (though I sure you could dig something up with a google search), but I had a good experience with a community ed class, and, of course, there's always the public library.
But just to get you started, here are the very basic basics:
I find myself shooting in AV mode the most, because I usually approach a picture by thinking of what kind of depth of field I want. Do I want everything in the photo to be sharp and in focus? Or do I want to draw attention to one specific thing by keeping it in focus and making the background blurry? Occasionally I'll want to stop motion or capture motion blur, in which case I'd use shutter-priority setting.
If you shoot with a large aperture (say around f3.5 -- just remember the lower the number, the larger the aperture), you will have a narrow depth of field and the background will be blurry (make sure you've focused right on the area you want to be crisp). If you want everything crisp, you need a smaller aperture, like f11+. Since this doesn't let as much light into the camera, you need bright light if you want to stop motion or if you're hand holding the camera.
Once you flip your camera's dial over to AV and choose your f-stop, it will automatically meter how much light it's letting in and set the shutter speed accordingly. Shutter priority (TV) mode is just the opposite -- you set the shutter speed and the camera will automatically set the aperture necessary for proper exposure. Go outside and pick a subject and try shooting it at f2.8 (or however low you can go with your lens), f5.8, f8, f11, etc. You might want to write down what settings you use with each shot so you can compare it to your results.
Note: This will all be easier if you're outdoors with good light, otherwise you get in to flash or long exposures which just complicates things at this point. Have fun experimenting. You'll learn the most by getting out there and trying for yourself.
