Today I found the Delphi Wiki. Not very full - yet - but still contains some useful info. It is waiting for your additions at http://delphi.wikia.com/wiki/Main_Page.
Also, Deepak Shenoy's blog entry on live templates and PInvoke contains many useful links:
- Deborah Pate: Creating live templates in BDS 2006
- Daniel Wischnewski: Creating a Script Template Engine for the Borland Developer Studio 2006
- Delphi Wiki: Live Templates Technical Info
