Taking a FA/CPR certainly can't hurt, but I've found that it's necessary to do it regularly if you're not someone who uses it every day, like an EMT. I used to take CPR training every year when it was offered at work, but they've since discontinued the program and it's been many years. Heaven help the guy that's looking to me to save him from a heart attack (actually, I probably do remember enough to do some good). I've talked to others that have said the same thing.

As for the amateur radio license, there are ham clubs all over the Chicago area. Talk to anyone with a license and they can put you in touch. They're usually more than happy to help someone else get licensed.
