Thumbnails certainly aren't being stretched - Perhaps you have a link to your gallery with thumbs so I could take a look?
You can set thumbnails options in the main config, but we left out compression control - We will add it for next release! Default compression is set to 80.
When you speak of the thumbnails quality, you are sure its not related to when rolling over a thumbnails so it scales up? That will of course create artifacts in the thumbnail. In my opinion, the default compression looks pretty good ...
