hue/sat adjustment layer in Softlight, overlay or any any mode you like
B&W adjustment layer in Color mode (will vary the intensity of colors)
image/adjustment/match color, don't pick source, just check "neutralize" or "natural" something like this, I don't remember, at work now, will give you very quick white balance and gets rid of color shift, works most the the time
use warp tool under edit\transform in addition to liquefy, gives you more control for particular situations
Breast enhancement, also known medically as "breast augmentation" , draw marque circle big enough to surround the breast, filter\distort\pinch go to -7 to -100, depends how big you want it to be, if happy with resolute, use the move tool, drag the marque circle to the other breast, go to the top of the filter menu, "pinch" should still be there, click it, it will apply the same amount to the other breast.
to speed up Liquefy load and get very big brush (the bigger the brush the better in liquefy) draw a free hand selection around the area of interest to select it, go to liquefy, only this area will be there and FAST.
I don't know what version of PS you have, but, for all versions, select the layer mask, make sure it is active, then, adjust the layer opacity, this will adjust the mask opacity without affecting the layer opacity, only the mask.
