Need help getting rid of columns on forumdisplay.php

[yoyoyoyo]

I am trying to edit the forumdisplay page down to bare bones. I do not want the first 2 columns (before the topic name) or the last 3 (after the topic name) I also do not want the poster's name displayed. I basically just want the title of each post to be displayed, and nothing else.See attached screenshot for more of an idea - I do not want the boxes that are crossed out, or the poster's name to appear. I have searched my way around the forum display templates but can't seem to find where this exact coding is. Any help is appreciated.

EDIT: I also want to get rid of the "last post" column on the subforum forumdisplay.php display like the attached screenshot, also
