Yes, you have to worry about all of these things, though probably not for the first three to four years of ownership. If you got the car for a big discount and it cannot be registered to you for six months, that's because you have bought a car originally sold to a fleet at a fleet discount on condition it has to be registered to the fleet for six months. You will have to declare to your insurer that the car is not actually registered in your name. Speeding and parking tickets will not come to you directly, possibly resulting in late payment penalties.
