ֵThe best combination, IMHO is PostGIS for the database backend, and 
Openlayers for displaying on the web. It's certainly possible to display 
GRASS vectors directly on the web, but, unless there's some specific 
reason to choose this option, I wouldn't. It puts an added complexity 
into the toolchain.
Finish your analyses in GRASS, then export the vectors to PostGIS, and 
call the PostGIS spatial layers from a webpage with the Openlayers 
javascript library.
I don't think anyone can give more specific guidance until there are 
more specific questions.
