Re the up or down issue, I think it is both.
I believe this was played with pick and (3rd) finger - that is the only way you can get the emphasis on the right note (the emphasis changes according to the phrase)
When playing this way it would appear as being played on the down stroke although the third finger is picking on the up stroke.
In any event, this is the only way I can get it to sound authentic.
Kind regards
