My pinch of salt to this forum would be to see the issue from 2 different stand points.

1. Although you won't be penalised hard for similar pages, it is clear that template pages from dynamic websites with complex URLS are penalised as they rarely show up in the first 3 pages. A different title would help.

2. Google is now making Webmasters understand that they should clean their mess. May it be from obsolete pages or duplicates, the site maps and txt files must be constantly updated. In your case, i would txt the directory containing these pages.

Then you're safer

Have a nice day
