What kind of personal questions are asked of potential jurors? I mean other than your basic info.

It really depends on the type of case you're a prospective juror on. The purpose of the questioning in jury selection (aka "voir dire") is to determine if a prospective juror has any preconceived notions or bias that would affect their ability to sit as a fair and impartial juror on the case. Typical questions would include:

The basics:
What do you do for a living?
Are you married, single, widowed or divorced?
Any children? Their ages? Their occupations?
Any friends or relatives in law enforcement or lawyers?

Then depending on the crime involved:
Have you or anyone close to you been accused or the victim of the same type crime as the one in court?
(if relevant in the case): do you drink alcohol? Do you or anyone close to you have a problem with alcohol?
Have you ever been arrested for any crime, even if charges were never filed?
Have you ever been accused of similar conduct as in the case in court, even if it never got reported to law enforcement or the court system?
What is the last book you read?
Do you have any bumper stickers on your car?
Do you listen to any talk radio programs other than news programs? Which ones?
Are you a member of any group whose purpose it is to make changes in the law (i.e. MADD or other similar groups)?
[if applicable]: Does the fact that the defendant or witnesses may use the services of a interpreter to assist them in testifying in their native language cause you concern about your impartiality?
Do you, for any reason, have an automatic bias just based on the nature of the charges against the defendant in this case?

You get the picture. It's designed so both sides get a glimpse into your life and make an informed choice on whether or not they think you're "right" to hear the case or if you have something in your background or mindset that gives them concern about your ability to be fair & impartial.
