Ok, i understand that if I want to use an ipod as my signal generator, i need to buffer the signal so it's mic level using some resistors.

Here's another thing I don't quite grasp;
I take a stereo 1/4" male ended headphone cable and strip the wires resulting in a hot a cold and a geound?
Which goes to + (goldfinger 10) and which to - (goldfinger 8)? 
What about the ground?

Hi,
Output of your ipod is stereo, so three cables are: L-channel, R-channel, Ground
If you want to feed some signal into MONO preamp you just need one of the channels and ground. Tie cold pin to ground:
* Pin 10: L or R channel of the ipod
* Pin 8: GND

Hope that helps
