Nodes aren't directly related to downloads, because most of the files on Share have already been uploaded to a neighbour of the original uploader who in turn may have uploaded it to other neighbours. Cluster words are key, but it looks like you are doing OK there. Beyond that, you just need to look at the Status and Order columns in Downloads. Status tells you if Share has found all the pieces, and Order tells you your place in the queue. I think all you have to do is be patient at this point. Leave Share running, and you'll move to the front of the queue soon enough.
