what is the difference between an ethernet cable and a rollover cable? and is there a diagram with the pin positions and colors?

I think you mean a "crossover cable" which simply means that the pinouts are reversed. (there are only 4 of the eight wires used in an ethernet transmit/receive cable).
Do this - grab a normal patch cable and put the ends together in the same position (clips down) and you will see they are identical in the way the colors of each wire are layed out in the jack left to right (usually starting with the orange/white wire). This is called a straight through pinout. PS: If they don't match you have a bad cable or a crossover. ;) Continue...
A crossover cable transposes some of the pins - wires/pins 1,2,3 and 6. Hold a crossover cable in the same way and you will see the different layout of the wires (noted by color). It is not identical as the standard straight throughs are.
Also, the pairs used are (the four wires for device communication) are the orange pair and the green pair.

An ethernet cable is wired straight through, a CROSSover cable has the wires twisted so you can connect a computer to another computer.

The previous answers are correct. To elaborate a bit, you'd use a crossover cable to connect two similar devices, such as an ordinary computer to an ordinary computer, a router to a router, ect.
