Secondly, your mock up is ignoring that you can have multiple of each piece in the pile. Does the checkbox apply to one or all?

I think it is important to think about how a user would want to sell his individual pieces. For a particular file, each piece has the same value, so there is no reason to have to enter separate parameters for each piece. Most importantly, I think it is clear that a user will only care to do one of two things:

1) Sell all pieces of a particular file

2) Same as above, but keep 1 of each unique piece.

Next to each file on the moar page you could have a link for 1 and a checkbox for 2, or two links or whatever. This would bring them to the page to enter the auction parameters. You could allow the user to set default preferences for these parameters as well as the “keep one of each piece” parameter. For starting price, that could be a percentage of the max starting price. This would make possible one-click selling for all parts of a file. For the seller, this would be extremely efficient compared to the current method of extracting each completed file and selling them in the ppwn shop.
