you can get a Roth-IRA, a retirement account. then, when you get a job, you can start putting money into the account now, so you'll have money saved up for when you retire. even if the company you work for now has their own 401k plan, it doesn't hurt having your own retirement account, in case the company were to go under.
any bank can help you, but I got mine set up with Charles Schwab. they do a good job breaking it down and what you need to do.
