If you are shooting in jpeg just so you can get the photos too the client faster, I guarantee they aren't as good of quality as they can be and if you are having the issue of taking too many photos too process, then you need to focus on better quality images, and less quantity.
Mind you I am not a pro, nor do I make a living from photography, but would one day like too, I am a very enthusiastic amateur photographer, for now.
As I said earlier, I use Lightroom (Currently LR4), to process my images. After I import them, I quickly go through and weed out the ones I don't like, at this point I'm not too critical because if I capture the moment, but the lighting is off, I can always bring it back in the editing process. Once I narrow it down, I go through them individually and process each one. I will eventually be putting out a video on this and let you watch as I process some of my images.
I always make sure the camera settings in LR match the camera and lens that I used. I then start from the top and work my way down the sliders on the right hand side, starting with exposure. I almost always bump up my contrast between 30-50, sometimes higher for black and white images. Everyone is different and will process their images differently, but this is the way I like to do it.
The best thing about shooting in RAW mode is that I can tweak an image anyway I want too and always be able to revert it back to the original, or export it halfway through, or if I process it, print it, don't like it, I can go back and make the correct changes without ever affecting the original file. And always make sure you have a back-up for your back-up!!
Below is a screen shot of a before and after, left is original and right is processed.
This is just an example of how you can make an image pop with color, without over doing it, check out the levels of the sliders on the right for how I processed this image.
