Re 'was a go-around attempted?' - it seems to me there are only two ways that people could come to this conclusion in the absence of any survivors and before the FDR is found. Either the captain told the tower he was going around - unlikely since surely that would have been disclosed at one of the press conferences - or someone inferred that from what they saw and heard. And to Joe Schmoe on the ground wouldn't max reverse sound a lot like take-off thrust? So as I see it there's no evidence in favour of the g/a theory, and a bit of evidence against from the video.
