Yes, you should be able to add :focus pseudo classes to your skin if you want to, and still have it override any other CSS files linked to the document. It looks like the media player skin CSS is declared after all of the others, so it should override any of the others, including your custom ones added via HTML extension at the root of the title. (see attached pic.)
As for the CC button getting stuck on tabbing, technically, the next thing that should get the focus would be the input elements in the CC menu (none or English). I don’t know why those are getting skipped, but they get skipped in all browsers, not just IE. (The issue has multiple factors as it is written up in the bug database.) I did try setting display to “none” for the CC button, and you are then able to tab past it in IE.
