Ok here is what I learned in school. ( Photoshop class, my well learned $1500 at work here O.o ) The Adobe PSD file is located on my website so you can view it with the layers and adjustments in tact.

Use eyedroppers, set the black eyedropper to 5 RGB across the board, set white eyedropper to 245 RGB across the board. Select darkest shadow with black eyedropper, whitest highlight with white eyedropper, then click around with the midtone eyedropper until you get a good color. You are looking for an 18% grayish color with your midtone eyedropper.
Selective color adjustment layer.
Next I did selective color adjustment layers for the blues, greens and cyan tones. This is a "please your eye" type thing. I liked the values I got for these colors you might adjust them for yourself if you prefer different levels.
Dodging and Burning
Create duplicates of your picture (layers) Set one to screen and one to multiply. Multiply is your burn copy, making things darker. Screen is your dodge, making things lighter. Add a mask to each, black it out and use a paint brush at like 20% opacity to add your color from your burn or dodge to your photo.
More detailed instructions on this dodge and burn are in this thread here including the mysterious location of the "Screen" and "Multiply" settings which I couldn't find before my class.

I sharpened the base photo with Smart Sharpen filter and I added sharpen edges to each of the dodge and burn photos also.
Note: I left the original untouched photo at the bottom with the layer turned off. This is how we are taught to do things at school so we have the original available if we need it again to add something later.
