One option is to list it on ebay as a whole bike after the defects are taken care of. And, yes, it sounds crazy, but not when you look at the individual bids in the auction you mentioned. There was someone (with 42 feedback) bidding and bidding and bidding and fell about $20 short at the end. He/she might want your bike at close to $700.
As far as touring framesets go, in my experience, true loaded turing framesets like this (canti brake bosses, lowrider attachments on the fork, dual eyelets on both dropouts - single up front may be ok- plenty of water bottle attachments) sell for about twice as much as a road frameset with the same tubing material. Do the math and see where that gets you.
Another option is to start the auction as a frameset at a pricepoint you are comfortable getting. These days ebay does not charge extra fees based on listing price.
Before I forget
: If you are planning on selling this as a frameset, you should remove the bottom bracket. Touring crank preferences are all over the place and a perspective buyer who is willing to build it from the frame up will see the BB as a PITA instead of added value.
