My wife was a bit of a "data addict" during her pregnancy as well. Sometimes this is not a good thing if it leads to undue stress. Fortunately we had a great doctor that answered all of our questions completely and gave us the basic rule, "don't freak out unless we freak out". However, there were other times that my wife's addiction to information was a very good thing. Either it let us know when to contact the doctor's office or put us at ease (normal pregnancy stuff).
I would highly encourage you and your wife, with your new found knowledge, to talk to your doctor and get specific information about your pregnancy and when your doctor's office wants to hear from you. I can't emphasize enough, get specific information. Exact blood pressure readings, headaches, kick counts, etc. During the course of the pregnancy this information will help with some of the mental stress that you're going through and hopefully alleviate some of your concerns.
Also, if you're not comfortable with the answers that you get from your doctor you may want to consider a move to a perinatologist (unless you're already seeing one). You seriously need to be comfortable with your doctor and have full faith in their ability to manage this pregnancy.
Continue to take it one day at a time and know that there are people out there praying for you guys too.
P.S. If you really want your wife off-line, I can give you ideas of some places to hide the computer!
