Choosing the right motor controller for my motors.. guidance

Hello,

So I have an Arduino Uno r3 and deciding on purchasing these motor kits http://www.parallax.com/Store/Accessories/MotorServoControllers/tabid/160/List/0/SortField/4/ProductID/587/Default.aspx?txtSearch=ball+caster

Would they work with the SN754410 motor driver ?

and will these batteries work with the motor?
