Spooning is a pain in the ass, I wouldn't attempt it. I would look for another shop, normal for a nonstealership is $20 per if you bring them a wheel. Or invest in a no mar.
sportbiketracktime.com has a shop where you can get a pretty good deal on michelin track DOTs. Don't know anywhere with Dunlops.
