Also keep in mind that youtube uses really low bitrates (relatively) for their content and fairly poor settings, meaning the results on fast-motion gameplay easily may not be as good as you've hoped. But it shouldn't be quite that bad if it's flagged for hd.
But basically (as you've already seemed to guess), you take the massive raw output, reencode intermediate (as transparent as you can) so you can upload it, then youtube reencodes it. Honestly at the bitrates we're talking about, you could probably use almost anything for the intermediate step. But yes, you should also change it to 30fps during intermediate.
