I am a 2009 Rutgers Camden grad who is currently clerking for a federal judge. The job prospects for the top of the class are great, ranging from Biglaw to federal clerkships. Many average students end up with various state court clerkships and at smaller firms.
Almost everyone I knew was employed at graduation despite the crappy economy, but that is primarily b/c almost 50% of the class ends up clerking. As you can probably guess, RU-C does much better than RU-N and SHU in Philly. I also know people who ended up with Biglaw in NY and all of the reputable NJ firms (North and South). I must emphasize, however, that you have to be in the top of your class to end up at these more reputable firms (but that applies to RU-N and SHU too).
Thus, I don't think RU-N or SHU would give you any significant advantage over RU-C with regard to North Jersey firms, but they probably do have more connections with NY firms.
