1st off, no need for the rediculous font. We can read just fine. Bold doenst make it any more important.
As far as the speakers, no. You are trying to use a 1/8 connection which is too small. You will need to at least get an adapter. 1/4" adapter is what you need. With that you will be able to use your computer monitors, sure itll sound like ass but it will work.
As far as ALL of the rest of your questions. They can be answered with very basic research. Check the tweakheadz site. There you can learn a little more about audio. The forums and the MPC are exactly the same. You will get what you put into it. The manual does have info regarding how to connect and what connections to use.
