Power source for project motors regulators amps and volts

Thank You Slip stick, I do have one more question and that is if say all the motors need 40 amps in total and I want to add to it and also have other components on top of would I need to add a few extra mA to 40 amps? Also would this burn out the servos if they have too much current going through them or do they have some leeway or possible only draw what they need? Should I do one battery for the servos and one for everything else?

This is all the specs they have on the order info:
