Not in this group. :-)
Seriously, this group is more about the language and the tools than about
applications.
That said, you might start your search for help on automating Office
applications here:
http://msdn.microsoft.com/office/program/word/default.aspx
You should find some pertinent newsgroups as well.
You can go here for information on extending VS 2005:
http://msdn.microsoft.com/vstudio/extend/
IIRC, the way you proceeed to extend VS2005 is very different from the way
for previous versions.
As far as the other products go - I have no idea.
