I'm still trying to come to terms with what all the great new developments for Office Programability will mean (i.e. what should I use now, what should I keep an eye on for next year, what is just not relevant?) and I'll try and post some findings here.
In the meantime I'm going to compile a list of useful URL's here once I get a minute (useful for me that is, it you find it useful too then that's even better).
But the first one I have to mention is Smart Documents Made Easier for .NET Developers on MSDN courtesy of Vertigo Software
