I am completing the set up for my home theater and I need to know really how much amperage I should pull from my box.

setup is

Integra 9.8 pre amp

4 each XLS 602 amps
1 each XLS 2202 amp

Optima HD-20 projector

Home theater computer with 650 watt ps

other items with little draw
BD player
xbox 360
cd player
playstation 3



I can pull up to 4 dedicated 20 amp circuits from my main panel before I have to add a sub panel do you think this will be enough amperage for all my stuff? my main concern is that I don't know how much power the amplifiers will draw under heavy load during reference level movie watching.

I think you will not have to add a sub panel.  Check this chart out http://crownaudio.com/pdf/amps/139718.pdf
The 8th power levels are where you will normally be at, or most likely below.  The 3rd power levels are when you are being blown away.  The amps, projector, and computer are going to be what draws the most power, the rest should be pretty insignificant in comparison.
