A very good resource for home group leaders, assistant leaders, people who lead worship in a home group, those who host a home group - basically anyone who is involved in a home group - is www.smallgroups.com
Most of the material on the website is for free, but you'll need a paid subscription to access the Bible studies and some of the articles. KVC has a subscription, email the home groups coordinator Margreet if you'd like to download any of these materials.
