For the first issue, my suggestion is kind of a medley of suggestions. I think you should post the stories onto the forums, AND post a downloadable file within the topic just in case your readers want to save it to their computers. (this suggestion acutally goews out to all the writers out there)
For the second one, I think it's more psychological. I saw a discussion about this earlier somewhere on the forums, that the conclusion they came to (which I kinda agree with) is that people are more likely to reply if you post the story as a topic. "I'm in the topic, so I might as well post a review" is the thought going here.

That being said, my other suggestion (which is actually mine) is that writers should post the stories to the forums, and then set up a reply topic for that story. Example:
Desperate Girl (Actual Story)
Desperate Girl Reply Topic (the topic for posting reviews for Desperate Girl)
Like I said, this is just a suggestion, and I don't see this happening anytime soon.
