The problem with taking on Script Fic as a serious venture is that scripts are meant to be performed by people, not just read like with prose. Scripts CAN be interesting, but usually it's only to people who are open-minded, or in the performing arts and therefore exposed to lots of scripts anyway.
As for actual details, it depends a LOT on the writer: Many scripts have lavish details and pinpoint their actors' directions and emotions to the letter, while others can verge on a free-for-all with minimal sets and description. Most are somewhere in-between.
It's a very specific format that's supposed to leave a lot of things to interpretation, so your average fan is going to get bored VERY easily if they don't want to take the trouble to read the dialogue aloud, or if they're not used to scripts.
First off, get yourself scriptwriting software if you haven't already. Look into Celtx; it's free, and it gets the job done. Final Draft is another good program, but it costs a bundle. So unless you plan on getting really serious about scriptwriting, I recommend you go with Celtx.
For formatting and style, one really helpful book is The Hollywood Standard by Christopher Riley. You could also try googling to find free online resources for learning script format — I'm not familiar with said online resources, so I'll have to defer to other posters on that. In addition, many scripts are available online to take as actual format examples.
As for artshifted flashbacks, as well as other art-direction issues, you would probably handle that with a brief parenthetical note. Just put it at the beginning of the relevant scene, or wherever else is appropriate.
Seconding Celtx for software! I'm a theater person, though, so I'm not much good with film-specific terms. Most theater scripts are loosely formatted outside of the basics, but film format is probably more rigid thanks to Hollywood influence.

Hello. For the past couple years I've really wanted to write a Script Fic, but I don't know where to start. Does anybody have a guide on how to write script fic, like the technical terms needed, how to judge if it is the right length for an "episode", how do deal with flashbacks that involve ArtShift's (Theoredically, the show in the script fic i am making would be entirely animation. The entire first episode would be in the style of the series it's based off of, most of the series would be done in 2d style (with cgi cel shaded vehicles) that looks more detailed and more digital. The last two seasons would be done in the AllCGI style of the original show's sequal/reboot) etc.
