You can certainly do those sorts of things with C# and the System.Drawing namespace.

For things like adjusting the hue, saturation and brightness of images you should take a look at the ColorMatrix. There are examples on the web related to this.

As for changing the textiles, I would think most of this is done using png's with an alpha channel. Again you can use the ColorMatrix to adjust the alpha transparency of an image. But I just think it's using masks to apply the texture to sections of the picture. I'm not exactly sure how you would go about this without p/invoking a bitblt, but I'm sure there are methods using .NET. The easiest way would be to split the image up into separate parts and painting them as layers over each other. The textile is overlayed, this can be done by having the image and textile at 50% alpha.

The Bitmap.MakeTransparent() method may also be of some help.
