Bring music mixer & speakers to new apartment; set up mixer

This is a unique task - it requires a basic understanding of how to hook up a piano keyboard, speakers, and microphone to a mixer.

- Here's the scoop: I have a microphone and mixer set up at my old apartment, next to an electronic piano.

- I have an electronic piano at my NEW apartment, so you would just need to grab the microphone, mixer, and speakers (smallish/medium sized speakers) and bring them from my old Russian Hill apartment to my new Union Square apartment.

- And then just hook up the microphone, electronic piano, and speakers together into the mixer!

- Bonus points if you can show me what kind of line-in wire I need to buy in order to record music directly from my mixer into my Mac laptop. But this is extra credit.

I am not very tech savvy, so this is a struggle for me, but I think your average guy would know how to do this. :)
