Read all you can. I agree with Derek that exposure is key; people don't buy what they can't see or find. You'll need to find someone to either write or at least review the contract. You'll need a disclosure statement which meets state standards. You'll need to know the rules of Fair Housing for advertising to ensure you comply and stay out of court.
I'd also recommend you consult with some local agents. First, if they know you are on the market, they may have a buyer. Second, if after trying it for a while on your own, you decide to list the home with an agent you'll have some options to consider.
I also want to point out some safety concerns. When I as an agent bring someone to a home, they are almost always pre-approved by a lender and cleared as a credible person who is capable of buying. As a FSBO, you'll be allowing strangers to tour your home without knowing their true intent. The majority will be interested buyers, but there are also drug seekers, petty thieves and con-men. One benefit of an agent is to minimize your exposure to these and to add a degree of safety for you and your family.
