Not the pro like SWG, but second dpreview.com. They also have some good articles deep on the site. Be careful there though, a lot of the talk is on the minutae of the equipment and the best specs.
Good to learn about ISO, aperture (F#s) and shutter speed to get some of the basic mechanics you can control.
For example, SWG is making a suggestion for a cycling pic because of his knowledge of camera controls (And I am happy to be corrected by him). Specifically, that level of ISO is "relatively fast" - ie reasonably sensitive to light to capture pics in daylight more quickly but not so high that you get less sharp pictures. For example, in a low light restaurant, you might use ISO of 800 to capture a pic without a flash, but the shot will lack detail (and some call this "grainy:).
A mid-level aperture of F4 is reasonably wide so it lets good light in so you can get a moving shot like cycling to be in focus quickly, but also allows a lot of objects in the pic to be in focus (called depth of field - ie how much of your fore & background is in focus). A wider F stop or aperture like F2 means that your lens opens wider than F4, which is good in low light, however in daylight with a wide aperture that means a narrower area right around your focus spot will likely be in focus. Sometimes that is a pretty look, but it can be unforgiving with moving objects, etc. SWG may have other reasons, but perhaps that gives you a flavor...
Anyway, besides learning what ISO, aperture, and shutter speed do for you, composition (ie what you choose to place in your pic) is a good concept. Lastly, lighting which I don't know much about and need to learn more about!
Some good simple articles are available with some simple web searches and plenty of nice books on the topic. DPreview has some good ones.
