Style disabled button with CSS

I’m trying to change the style of a button with an embedded image as seen in the following Fiddle:

http://jsfiddle.net/krishnathota/xzBaZ/1/

In the example there are no images, I’m afraid.

I’m trying to:

1. Change the background-color of the button when it is disabled
2. Change the image in the button when it is disabled
3. Disable the hover effect when disabled
4. When you click on the image in the button and drag it, the image can be seen separately; I want to avoid that
5. The text on the button can be selected. I want to avoid that, too.

I tried doing in button[disabled]. But some effects could not be disabled. like
top: 1px; position: relative; and image.
