CSS changes btwn ProsePoint 0.29 and 0.35 upgrade?

i've recently updated my site from ProsePoint 0.29 to 0.35 and am noticing that the text formatting looks slightly off.  for example, on an edition composite layout, the headlines now look smaller and the source links look completely different.

v0.29:
http://www.westwellproductions.com/barkadako/NSFP_ProsePoint/edition/fea...

v0.35:
http://www.nsfreepress.com/edition/features/366

any tips on how to get the new site to look more like the old site?  which css files do i need to edit?  sorry for all the questions.  still very new to ProsePoint/Drupal, etc.
