Glad to hear it :)

Yes. In grass each functionality is wrapped in a stand-alone module. 
There are library functions that will allow you to set up a standard 
GRASS command line interface. See [1] for the programmer's manual. Also 
have a look at the example raster module to get an idea on how to set up 
the module to be a GRASS module, and how to access the GRASS raster files.

Definitely grass-addons for now.

Looking forward to it. In the meanwhile I'll be happy to help you in 
case you have any more questions.
