Yes the one with 1.5A and 1.56ohms sounds much better. What that page calls "operating voltage" is only the product of these two numbers, not the "real" operating voltage which the motor is to be supplied with.
About the consumption, dunno really, but could take like 1A in budget for each motor. For an 20x20cm bed you would need at least 100+watts, you need to know how much resistance it has in order to see how much current it draws. I dont know if that 203w is the input power or the output power. But i will guess its an input power, and like an smps will have an efficiency lets say 75%, then the output is more like 12.6A instead, which likely wont be enough.
