The "light rail" that runs through campus is a streetcar (the Gold Line) that only runs for a total of 1.5 miles. It connects at one end to the Transportation Center, where one can depart/arrive on the city's bus system and the actual light rail system (the Blue Line). Fare information for buses and the Blue Line can be found here:

Try looking on Craigslist for apartments in the Elizabeth, Chantilly and Plaza Midwood neighborhoods.
CPCC also has multiple campuses. Some programs/classes may not be offered at the main campus.
