I have studied alot of photoshop tutorials and have been making notes along the way as and when I came across something that I deemed to be useful.
Here are some of the notes I have made collected from various tutorials. The tips n tricks are written for my own benefit using phrases and terms that make sense to me when talking about photoshop. They may not therefore be written grammatically correct.

Creating a Clipping group to isolate an adjustment layer.
Clipping group.
To isolate an adjustment layer so that it effects just 1 layer, you can use a clipping group.
This can be done by holding down the Option key and putting your cursor between the layers and clicking once whilst holding down the option key.
Clicking between the adjustment layer and the layer you want the adjustment layer to be grouped with in the layers pallet until the clipping symbol of 3 circles appears.
The adjustment layer will now only effect the layer which it is grouped with.
Isolating an adjustment layer using a mask - (alternative to using a clipping group)
Adjustment layers load up with masks pre loaded so rather than creating a clipping group, you could just select the area which you want to be effected and mask out the rest.
Decrease healing brush smudges / dark circles under the eyes
Using the clone stamp, set the mode to lighten, click on a light tone and paint in under the eyes with an opacity of about 30%.
Increasing contrast in the Eyes/Bringing back and adding contrast to facial features
Levels adjustment layer, raise the shadows and bring up the highlights a little, (CMD + I) inverts the layer mask to black, then set the brush tool to white and paint over the eyes to reveal the contrast eye.
Creating dark circles around the eyes
(Shift + opt+ CMD+E) to create a new layer, (opt + click) to oadd a black layer mask o the layer. Set layer style to Multiply, paint in a dark circle around the iris, reduce the opacity until it looks convincing. This can help the eyes to "pop".
Correcting skin tone mis matches
Select the paint brush tool and set the blending mode to Hue. The brush will now only effect the colours of the skin and not the luminosity. Reduce opacity to approx. 30%. Using the colour picker select an appropriate skin tone and paint over the areas of skin that are too picnk etc. (great for ears and nostrils).
Reduce blood shot in the eyes
Healing brush, choose a small brush and paint over the blood shot parts of the eye.
Dodging and burning
Start with the burn tool, ensure that protect tones box is clicked and that midtones is selected in the range box, paint over the shadow areas to darken them up a little, following the bone structure of the face. Use a low exposure, something between 15-20%.
Use the dodge tool to paint over the highlights in the same way as the burn tool.
Try setting the layer style to luminosity to see how this effects the image, sometimes gives a beneficial change to the skin tones.
Liquefy
Liquefy is found under the filters menu.
Use the forward warp tool to make adjustments to the edge’s of the face, the jaw line for slimming effects.
Use the pucker tool to make the nose smaller.
Use the bloat tool to make the eyes a little bigger.
Use the reconstruct brush to revert the area back to its original state how it was when you opened up the liquefy dialog box.
Pen pressure
When using the brush tool you can turn pen pressure on or off by open up the brush pallet by clicking the icon which can be found next to the brush size and selecting shape dynamics.
Content aware fill
Some large area’s can be taken away from the image using content aware fill. I have found that in the right circumstance, this can save a lot of time !!
General tips for a good PS workflow
Create copy of original image
New layer, choose fill in the menu and fill with history.
Use an Intuos4 graphics tablet to give you further control over a mouse or touch pad.
(Shift + opt+ CMD+E) creates a new layer containing all the visible layers
Time savers
Opt + click the layer mask icon to bring up a black layer mask
Fill with fill dialog box
Press Shift + Delete to create a fill and open up the fill dialog box to allow you to choose the colour and change the blend mode of the fill.
Creating a Lighting effect from scratch
Make a gradient, filter – Render – difference clounds. Image – adjustments – invert, Image – adjustments – levels, bring down the blacks and the midtones,
Add colour by image – adjustments – hue/saturation, click colourise box and adjust the Hue to add colour.
