TieredMergePolicy is the default even though it's commented out in solrconfig, it's still being used. So there's nothing to do.
Given the size of your index, you can actually do whatever you please. Optimizing it will shrink its size, but frankly your index is so small I doubt you'll see any noticeable difference. They'll self-purge as you re-crawl eventually. In all, I think you can mostly ignore the issue.
