I don't do weddings as a general rule, I'm a portrait shooter. The healing tool in photoshop is my tool of choice for retouching. I do this separately from the basic processing (contrast, color, exposure adjustments, etc) that I do with the RAW file in Lightroom. I have both LR and CS6 open on at the same time so I can quickly switch back and forth between the two. But honestly, unless we're talking about a teen with a lot of acne I don't have a lot of retouching to do in my portraits. I learned the hard way (after doing an entire shoot with power lines in the background because I was careless) it's a whole lot easier to head off problems when you can before you take the shot than to deal with them later. Sometimes that includes fixing makeup, sometimes that means taking care of a stain on a shirt (go Tide pens) and sometimes it means making the lighting more favorable for the subject. But you really can head off a lot of issues if you watch for them when you're shooting.
