How do you style the topics titles and content in Forums plugin

I installed Forums plugin on a site using twenty-twelve as the theme.

When I add topics the topic title is in very small font, and the page is not laid out the way I would like. Where are the setting for actual page styling, not just the Forums settings page?

It's on as well as the topic pages at:

An example is at:

With the Topic title saying "Topic 1- Q1: CTE & STEM Integration in classroom" in something like 4 pt type.

Also, how do you style the forum page elements?

How do you reorder the list of topics?
