Those old notes are still legal tender and any bank should be able to exchange new notes for them.

As for pennies, the rule is that you can still use them as long as you round up/down to the nearest $0.05. However, I've found some stores to be quite unintelligent and have just refused to accept any pennies. It's on a case-by-case but if you're going into a bank anyways, you can exchange those pennies for nickels and dimes.
