A little leg work shows that the version 3.5 factory defaults for the following paragraph styles are...
List: (nil) -- inherited from Text body (apparently, the same settings as Text body)
List Contents: Indent left 28pt, Indent right 0pt -- inherited from Default
List Heading: Indent left 0pt, Indent right 0pt, Next style: List Contents -- inherited from Default
List Indent: 0pt + Indent left 14pt, First Line 128pt, Indent right 0pt -- inherited from Text body
BTW, Text body's defaults are: From top 0pt, From bottom 6pt -- inherited from Default
