| 1/2" is actually pretty good range for a basic reflectance sensor. try using them in the analog inputs -- you should get readings that let you read out to about 1". to get better than that, you need a modulated signal, like Pandit has described.

I.e., the fact the motors are on the red direction means nothing; it's just the random state of the motor output latch when the board turns on without a program. The LCD screen should not (...)
