Sounds like you have the right setup, then. Just get an adapter cord with 1/8" stereo plug on one side and RCA jacks on the other and you will be in business. You can get one at RadioShack or any other electronics store. They also make an adapter that goes right at the MP3 player with 1/8" male to twin RCA female, but that can be a bit bulky.
Since the jacks are on the back of the radio, you may want to wire an 1/8" female jack onto your dash and hardwire it into the back of the radio. Just make sure it's protected from the elements. And the advice about keeping the MP3 level down is good. Overdriving the input can cause a lot of distortion since RCA inputs are line level rather than a headphone level like the stereo jack on your player.
