Brian,
Read the manual, attend the tradeshows to see demonstrators perform on and explain the equipment, or drive to your nearest professional DJ equipment dealer and ask the salesperson to show you how the equipment works. Pioneer also offers an instructional video that utilizes the gear you have purchased.

Also check out this website for great tips.

In case you haven't seen it anywhere else.....Practice and be creative(try to be creative in the privacy of your own home as you want to be on mark in public)

If you want a detailed message on the players let me know but read the manual first(most people skip this and just jump in but if you do that, you'll learn slower. It is better to know what you are doing and why.).
