Again, local vs national does not make much of a difference. The only extra views you would get one way or the other is through drive-by traffic (i.e. people going directly to the Examiner and browsing) and if you are relying on that, you are probably not going to make much regardless.
Both national and local will look exactly the same to Google, and that's where 80% of your page views should be coming from.

On formating, I would advice not using a word processor at all. More often than naught, it will cause problems. If you do use a word processor, paste it into notepad first, then copy it back out and paste it into the editor. This will strip all the extra formating 'noise' that word processors will put into it.
I wrote an editor for web writing:
http://www.myquicknotepad.com/
It's not fancy. It uses a quick wiki-like markup language and only saves the last article, but it is relatively easy to write something and create bold/italics/links/etc. You have to switch to the source view of the Examiner tool to paste in the HTML.
I work just as easily in HTML, so this stuff isn't tough for me. If you aren't familiar with HTML, you might look around for a solid web-based editor.
