I'm a little concerned that you have new lights and you are asking/talking about CS6. Your goal (or at least, a goal), especially when using studio lights, should be to get as close to the final product as you can, through your use of lighting & exposure. Don't start off with the mentality that you have to fix or enhance everything with Photoshop. Since you pretty much have control over the lighting, you shouldn't have to make any adjustments to exposure, shadows, background brightness etc...as these are things that can be controlled with proper lighting. Of course, it's not just that easy, especially with only two lights and a small space, but I just want to emphasize my point that you should be concentrating more on the 'before the shot' stuff, rather than the 'after the shot' stuff. It will pay off, I promise. As for the shots, plenty of good things and certainly room for improvement. The one thing that stands out to me, for possible improvement (or at least a different option) would be to use 'short' lighting instead of 'broad' lighting, like you have. With short lighting, the subject's face is toward the main/key light. This lights up the front of the face and puts the rest of the head into shadow. They way you've done it, you are facing away from the main light, so it's lighting up your head and only part of the face. Both ways are a valid style of lighting, but short lighting is often preferable.
