I was asked this question over on my blog, and to be honest, I'm clueless.I read your post. THE most important formatting rule is your manuscript must be easy to read and to mark up--12 pt Times, double-spaced, 1" margins, white paper, single-sided, page headers with name & page numbers. Everything else is a matter of preference.
I did a blog on formatting and mentioned putting the author's name, copyright symbol, and the year on the right at the top. That's what I've always been taught to do, then someone said they'd been taught to never use the copyright symbol and wanted to know if the rule has changed. Help?
The second most important formatting rule is to follow the preferences of your publisher/agent. These are usually listed on their website.
The copyright mark and All Rights Reserved are unnecessary. You have copyright protection from the moment you put your first word in tangible form. It is understood that all rights are reserved until you sell them. I'm a professional. I know this. You don't need to remind me. However, if it makes you feel more comfortable you are welcome to include this. I won't make fun of you, not even in my mind.
Everything else in your post is fine. I have a personal peeve with using style sheets in Word instead of the hard indent. I prefer the hard indent because Word can go all skeewampus when we convert it to our typesetting program and we sometimes end up with some paragraphs converting to a hard indent and some converting to a first line indent and then we have to go through and fix it manually. (If you're using WordPerfect, don't.)
