As far as I see, the upgrade worked correctly for you.

The errors concerning skin autodiscovery happen, because you still have old files in your wiki directory. Inside the folder skins/ you have exactly the mentioned files and one folder for each of them. These skins do no longer come with the new version of MediaWiki. The according files and folders should be removed. See also Manual:Upgrading!
