Tom,
As long as you have a high impedence earpiece (32 ohms) and an
electret microphone you should be fine.
I doubt if you are going to blow up your sound card whatever you do...
4P4C connector and two 3.5mm stereo jack plugs should be fine.
Polarity of the mic is important, but again, reverse bias it and you
will probably live :)
Start off with music and headphones - that connector is the output
(probably lime green), and connects to the inner pair of the 4P4C.
Pink carries microphone. Screen to the 3.5mm connector will be ground.
The two remaining wires are bias and input to sounds card and need
connecting together (maybe with a resistor and cap), see

Good luck, sound like a fun porject.
Regards,
Mark
