Why won't the Colour Replacement Tool work for me in PSE5? I'm doing exactly what the Help says and it just does nothing. I'm just trying to remove the white sky from a photo. I've tried both the Background Swatch option and the Sampling once option.

Assuming your Color Replacement tool works the same as in my PSE2, the tool simply does not work on white or black. You said you want to remove the white sky; are you trying to make it transparent or replace with a sky color? You might try the Magic Wand tool to select it.
Here's how to create your own sky using a gradient:
1. Add a new empty layer.
2. Set the foreground/background colors to dark and light blue.
3. Select the sky using the Magic Wand or other tools.
4. Activate the Gradient tool with the options Linear Gradient and Foreground-to-Background.
5. Draw the gradient vertically from top to bottom of selection. The degree of the gradient transition depends on the start and end point of the gradient, so you might have to redraw it until you get the result you want.
Note that you don't really need to draw the gradient on a new layer; it can be directly on the picture layer. However, I wanted to demonstrate that the gradient is solid and wipes out any clouds. If you draw the gradient on a new layer you can then change the layer's blending mode to other than the default of Normal; some of these modes will preserve the clouds and existing light variations to give some interesting results.
If you do create a solid sky you might want to add some clouds for interest. You can find some very realistic cloud brushes at the Adobe Photoshop Exchange:
Enter "clouds" in the Search box. You can also do a Google search for "Photoshop clouds brush" or similar.
Here is an example using a variety of cloud brushes:
In order to place the clouds behind the lighthouse and trees I first selected the sky, inverted the selection, and did a copy/paste to create Layer 1. I then painted the clouds on the Background layer.
