how do we affect the page layout for the classified page?

hello. I'm having trouble getting the Classifieds plugin to work properly. You can view the current version of the page here:

http://scmwine.com/classifieds/

Issues we've identified:

a) Title shows up above "normal" page title location
b) Featured image from 1st classified shows up above ad
c) unclear how to affect sidebar content

I started a support string last week here:
https://premium.wpmudev.org/forums/topic/im-having-some-formatting-issues-with-classifieds#post-486195

but as you can see have not had response in a few days.

I also just chatted with a live support person who suggested using the theme archive.php file to create a archive.classified.php file, which would somehow allow me to change things.

We could really use some help.

thanks!
