I assume that you have already looked at the Stickies over at forums.lotro.com
the Lua Scripting (Beta) forum thread -- about 2/3 of the way down the forums list.
There is also a pretty detailed "how to" by Garen:
Writing LoTRO Lua Plugins for Noobs.
The latest update from Narrel is the thread: Riders of Rohan Lua/Skinning updates. (Narrel is the Dev responsible.)
As far as I know he has not posted an the Riders of Rohan update he mentions, only the skinning update. Therefore the most recent API document is here (lotrointerface) in LotRO Tools & Utilities for Developers - the thread: Isengard Lua API Documentation
