Question 2:

Change your program so that the car will go backward for 1.5 sec. Use the new NXT green light to give your program a name.



In this solution for the 2nd problem, the regular greenlight is changed out for the NXT greenlight and a label with the program name is added.  This allows you to load more than one program and access them by name. Without this the name defaults to rbl and each new program overwrites the old program.
