You should be able to safely run apt-get autoremove, but shouldn't usually need to.

It's almost always a bad idea to run commands unless you explicitly understand what they do and how, including any output they post and decisions they ask you to make.

However, based on the list of packages you provided, I think executing the command would be safe. Initially there are a few older libraries, common dependencies likely superseded by newer, separately packaged versions, and old kernel versions, nothing to worry about unless you've start experiencing issues as a result of recent updates. Finally there is the old plank theme, which can be safely uninstalled since you aren't using it anymore.
