Are you talking about physically writing out the actual stories? If so, I wouldn't bother. I'm 600 kanji in and not writing any of the stories, only reading them on the website. The one day I was away from the computer and wanted to study straight out of the RTK book, I wrote the stories out in a notebook. But I didn't notice any retention difference the next day when I reviewed.

You should if you have a "writing" memory. For most of us, writing can help a little, but just a little isn't worth the trouble of writing the 2042 stories down. You have to know your memory works that way. Usually people who like to write have this kind of memory.
And all my stories fit on 21 pages (front+back). I'll try to share some pics (batteries are charging).

Only if you need to, and generally you won't.

I never found it useful.

Here are the pictures (I've wanted to do that since I completed RTK). There's one typical page and my four five-page booklets.

And what took me most of the time wasn't writing down the stories, but devising instant remembering stories (average, 5 to 10 minutes -- pretty slow, I know).

Writing them out is a bad idea. For one it reinforces English into the kanji which in reality could be detrimental.  If you're going to write, I suggest drawing pictures instead. A simple picture or series of pictures for a kanji can help ingrain the kanji into your brain via stimulation that is caused by the use of a pen/pencil and the reinforcement you get from seeing the picture take form and complete it's self. Keeping out English will help in the long run.
