Well, it seems like you got your questions answered, but I thought I would just say welcome. I do pretty much what you've done here... I link in whatever piece I use the prompt in. Sometimes that means one of my epic fanfiction pieces, and other times, I do a stand alone because the prompt refuses to fit into my long stories. As long as you write at least one story or chapter a week, you're on your way. And you may find that it's easier than it looks once you get in the habit of always writing.
