The American Red Cross and FEMA has put out this checklist that goes through everything you need, from supplies needed to making plans. It even has blank "rooms" for you to draw escape plans for a fire in your home. It also has a "home hazard hunt" section where you can look for things that could be potential hazards to your home.
It's 4 pages, and I highly encourage you to print it out and go through the list, even if it takes a few days. Remember if you are prepared, you will not fear.
