Lighting is subjective to where and what your doing.. You don't always have a choice in where the sun is or how dark it will be when you take a shot..
I personally don't like to edit to "remove" objects from my pictures unless it's a total must.. I try to position myself in the best place to start with..
It really depends on what type of photography you are doing.. People, landscape, macro or telephoto either stars or sports..
I believe in taking as many shots as possible and can burn off 25 pictures in as fast as my camera can keep up with to get the right shot..
Using a tripod is extremely important.. When you don't holding your Camera and lens as stable as possible will help greatly..
There are times when it's best to let your camera show you the best settings and be a man than to try to be the worlds best photographer. There is a reason for Auto and also for Manual..
Use the Photography web sites to learn what you need to know and listen to PODCasts if you think that can help you.
Most of all none and all of the advice will apply..
