Change multi-level bullet symbols - text sizes

I would dig further myself, but running out of time for presentation of the site tomorrow afternoon.

Can you direct me to where I can change those multilevel bullet symbols that are used when you use the indent on bulleted paragraphs? (First level are regular bullets, next ones unfilled, next ones square.) I just want the standard bullet on all of them - depends on what's on the page sometimes how far in I want to indent a bulleted list and want the same bullet symbol for consistency. I can put a manual bullet on the short lines, but on the multi-line paragraphs I'm stuck with the changing ones for the indent to work properly.

Also - I vaguely remember seeing somewhere (maybe in the editor?) where you could specify the sizes that would be used for small - medium and large text when the user messed with the Page - Text size command? Or am I imagining that?

Thanks for all your help, and I pledge to continue being a regular contributor!
