I responded to an email from a hacker posing as a friend in distress. I have a really long secure password ... caps/special figures/numbers/over 14 characters long. My account name is my first, middle initial, and last name. I just changed my security question to something I believe is not guessable. I have other accounts associated with my account that are not as secure (password not as long/no special figures or caps) and am going about changing their security questions and passwords. Anything else I should do? Do you think I'll be ok?
Based upon the information you have provided -- I would not bother doing anything.
This is most likely a social engineering attack, where they're going to try to persuade you to wire money via Western Union to some location where they (or a confederate) is ready to pick up the money. It sounds like you did not provide them with any useful information. Your email address and name is already information they could easily obtain, and isn't likely to be very helpful in attacking you via any method I can imagine.
You mentioned you already have chosen a long and strong password for your email account. That's good, and the main thing. I don't think you really need to do anything else at this stage.
If you have other accounts that you care about with a poor password, it wouldn't be a bad idea to change those passwords to something stronger -- not so much because of this incident, but rather because this is as good a time as any to do some basic security hygiene. Also, if you don't already use your browser's password manager, I encourage you to start using it. Password managers make it easier to use long and strong passwords, and reduce the temptation to pick something guessable.
This sounds more like a social attack. Having your email address and name doesn't get somebody much other than launching a targeted attack against your password. I would expect they were just looking for someone to wire money with no verification. There really isn't any increased risk to you at this point.
