I think I like the version with the left sidebar better. The reason is that the main content is not to the very left side but more in the middle. And, as Midas said, it is more compact.
Stars' placement is still a question to me. I would like to keep them together with the thumbsup and thumbsdown buttons. If they are on the right, with the "Updated by" info, then it is too large (and in 3 rows). Additionally, 2 items will be removed from the left sidebar, so there would remain only Add Comment and Edit this entry.
I would perhaps keep the main icon's border, put stars below and vote links too (as in the html Andrew uploaded for you). The border served good as a visual separator between the entries.
I don't have time to fully test it and apply to the other pages, so see you a week later
