Ok easy questions first. If a vehicle has a top speed of less than 20 mph, it's not considered a motor vehicle (at least not at the US Federal level). Whether you need a license or not will depend on your state/city.
These wheels are NOT designed to be supported from only one side (like a wheel chair) so you will need mounting brackets on both sides of each wheel. Since these are brushleszs DC motors you should be able to reverse direction by swapping two of the three power leads. The question then becomes, how do they sense motor RPMs and is this reverseable? Your best bet would be to ask the company selling them. Also ask about whether or not they will freewheel, my guess is that they will, but it's best to check and make sure. These motors are rated to produce approx 600 watts continuously, combined that gives your 1200 watts. At 15 mph you should be able to pull a loaded bike trailer and still not overheat. FWIW 1200 watts is roughly equivelent to the continuous power that 10-12 average american adult males can produce, or 4 to 5 males in excellent physical condition or 2-3 elite atheletes (Tour de France level cyclists). Joystick steering is possible but complicated with these type of controllers, especially if they aren't designed to reverse. Perhaps you could use "Tank Steering" with two levers?
