Chris Tilling requests some books on New Testament ecclesiology, here are some of the ones that I have found informative and helpful.
M. Bockmuehl and M. B. Thompson, A Vision for the Church: Studies in Early Christian Ecclesiology (T & T Clark, 1997) J. T. Burtchaell, From Synagogue to Church: Public Services and Offices in the Earliest Christian Communities (Cambridge University Press, 2004) R. W. Gehring, House Church and Mission: The Importance of Household Structures in Early Christianity (Hendrickson, 2004) L. T. Johnson “Paul’s Ecclesiology” in The Cambridge Companion to Paul ed. J. D. G.

Williams, Stewards, Prophets, Keepers of the Word: Leadership in the Early Church (Hendrickson, 2006) J. D. G. Dunn's The Theology of Paul the Apostle (Eerdmans, 1998) also contains a useful chapter.
Obviously we would here need to decide if our quest is to understand the historical structures and features of "church" in the New Testament, or whether we are looking for a conceptual and theological understanding of the Church. According to Mike Bird, Markus Bockmuehl has an interesting chapter in the recently released Scripture's Doctrine and Theology's Bible: How the New Testament Shapes Christian Dogmatics eds. Markus Bockmuehl & Alan J. Torrance (Baker, 2008). These are good entry points into the discussion of NT ecclesiology.
