Question about Outlook Express

First, what I'm using is Windows Live Mail 2011 with Windows 8.  The last time I posted a question I thought I made what program I was asking about clear, but still ended up being asked what I was using [wry g].

Also, all three of these questions are about plain text email as opposed to html mail.  Several of my mailing lists *only* use plain text, so I need to be able to work with plain text.

First question.  I need to be able to enlarge and preferably change the plain text font (as opposed to just using some sort of "enlarge" button that enlarges everything).  How do I do this?

Second question.  I need to set Live Mail so that it puts an > carat in front of each line of quoted text.

Third question.  How do I set an individual email to send in plain text as opposed to html mail?

I suspect that all these questions could be answered with a "this is how you adjust plain text email in Windows Live Mail" answer, and that would be best of all, because that way I could go through all the options and set everything up just right.

Help?  I've got the html mail working exactly as I want it.  Now I need to make plain text email do what I need *it* to do, too.
