Liability insurance is to compensate others for damage that you do to them and vice versa. Their automobile insurance depending on the amount of coverage and damage should cover any damage to the house unless they are underinsured or uninsured. In that case, you would need to file a claim with your homeowner's policy and they would pursue the neighbor.
I concur with Barry that you might want to look into a key person policy. I don't know if this type of policy is life only or it has some form of disability protection.
If it doesn't have the latter, then you might want to be looking at some form of short (quack, quack) or long term disability insurance as you have a one in three chance of being disabled before age 65.
You might also want to ask Biznik member Beth Cosker for her opinion as well as she has been successful in getting supplemental group insurance for Biznik members.
If you can't retrieve your data based on your last remark, there are a number of folks who can help you with that issue.
