Note: Certain terms used in my post refers to tools in Lightroom. For reference, I use LR 3.4. Never do I say that I am entirely sure of what this photographer did--I am just calling things as I see them.
The first one looks like it had a Tone Curve manipulation so it pops a little more. The blues in the sky look subdued--looks like he (or she) used the Camera Neutral profile in Camera Calibration, upped the Temperature a bit, and dropped the Blue Luminance a knotch or two.
Some portions of the clouds are blown while the rock that the bride is standing on seems pretty dark so I suspect that a fair amount of Contrast was added but it is hard to say for certain. It seems that some Sharpening was added too to help the textures on the rock and the dress pop.
Gradient filters might have been used to brighten and/or darken portions of the sky but it is hard to say for certain.
The second example that the OP provided looks more flat compared to the first one--almost as if the tone curve was left linear. Again, it looks like he (or she) used the Camera Neutral profile in Camera Calibration and also upped the Temperature a bit (the blue in the sky looks subdued but differently than the first photo).
It looks like some brownish sort of filter was placed over the image but I can't say for certain since I don't use the Photoshop CS3 (or any of the CS series) regularly. The brownish colour may be the byproduct of increasing Temperature as well but I believe that additional work in a Photoshop CS program was done to the image.
