I would say yes, it is a nice thing to have for emergencies, also just putting stuff you are going to buy on the CC helps establish a credit rating, just don't go stupid, like if you go out to drink or whatever leave it at home.
Also, you should look at getting a student line of credit over a loan.
I got the student line of credit from Bank of Montreal when I was a poor college student, interest rate was 1% BELOW prime, if that is still the same as it was back then, you'd be laughing :)
