Replacing front bumper cover

I need to replace the front bumper cover on my son's 2002 Alero - he pulled into someone while he is at college. I am wondering if anyone can tell me what tools I would need to remove / replace the cover, and if I would need a jack and jackstands? Can this be done in a parking lot, or should I try to do it here in the garage the next time he comes home? The car is still at his college, so I cannot see what it will take to do this job.

Thanks
